Graphics update:

• 3D arrow objects
• Coloring based on note timing (as in other dance games), beat effects
• Better track visualization (instead of the ugly texture)
• BGCHANGE support (background videos)

Gameplay:

• Proper mine support (currently buggy, matches too easily)
• Improved hold note/combo support + roll/lift notes
• 3D mode instead of traditional scrolling? (proof of concept in dance3d branch)

Core:

• 3D object stretching/repeating support for long arrows
• Clean up the dancegraph/instrumentgraph mess

HELP WANTED!

Proper positioning/scaling for text elements.

• Correct vertical alignment
• Use dimensions to specify bounding box (possibly init from SVG)
• Highlighted (current) lyric should be rendered in front of the others

I've tried to follow your instruction to build it under Mac OS X 10.8 ML.

I would say it is very hard task :) All dependency was installed via brew.
Not all of them cmake can find out, during configuration package. There is some problem with magick++, but that problem coming form brew bug. Most important problem is coming on compile stage:

/usr/local/include/boost/variant/detail/move.hpp:141:35: error: no member named 'move' in namespace 'boost::detail::variant'; did you mean 'move'?
rhs = boost::detail::variant::move(tmp);

Simialr erros are a lot on that stage.
Seems it is problem coming from compile flags, could you please advise me where and how (and which one) should I use?

Seems that flags can solve it http://stackoverflow.com/questions/13445742/apple-and-shared-ptr

Implement in-game song downloads to make it easier to use for new users.

WIP in git branch "torrent".

Various options still need to be configured via XML file. Provide GUI support for modifying these in-game.

Implement in-game latency calibration helper with the intention of making latency calibration as easy as possible.

• Audio roundtrip by analyzing the sound captured by the microphone (fully automatic)
• Controller/audio latency by playing blindly (listening to the beat only)
• Audio/video by playing visually without audio? (needs controller/audio calibrated)

We need a Windows build and also restore the CI system.

Building for Windows is hard because we have a) a huge pile of dependencies that need to be compiled first and b) no Windows developer.

For the past couple of releases, I have been cross-compiling the deps and Performous from Linux. However, my toolchain is now severely outdated and cannot compile Performous anymore. I'm now using MXE, which is nice in that it has build rules for all Performous' deps and also features an up-to-date compiler (in contrast to e.g. mingw packages in Ubuntu repos). I have tried to update the toolchain on several occasions, but it is hard: MXE compiles everything as static libs, but CMake doesn't handle recursive library deps, so I get a ton of undefined references. On the other hand, if I patch MXE to compile dynamic libs, compilation of some of them fails.

I have now added a mega hack to the build scripts that have allowed me to successfully compile and link Performous.exe. The hack uses pkg-config directly to fetch the private dependencies of the static libs and injects them to CMake's link command. I don't know why the CMake scripts don't do this automatically, even though they at least attempt to use pkg-config. Perhaps someone more intimate with CMake (@Tronic?) could shed some light, or even make CMake behave.

Regarding the exe, it doesn't start through Wine, which is unfortunate for testing. However, it works on real Windows, though it's rather buggy:

1. Menus render on top of each other
2. There is sometimes fullscreen flickering
3. Some images fail to load randomly, resulting in black boxes
4. Covers on the song browser sometimes leave trails
5. Popup menus miss background
6. Some other similar things I forgot

All of these seem to be graphical issues: I do get audio output and I also tested some instrument gameplay which worked fine apart from graphics glitches.

I'd now like to invite anyone who can to help:

1. Test the build and report if you have same/different/no issues
2. Any suggestions or actual work on fixing the bugs?
3. Any suggestions or actual work on fixing CMake with static libs?

Allow singers to hear themselves while singing. Needs audio syncing (big technical obstacle) and preferably some kind of reverb effect. Adjusting volume based on correctness could also be useful.

hi there (tapio might remember me from last time with the composer stuff see: performous/composer#3)

I'd like to add playlist support to performous for use at events or karaoke nights. in other words, while someone is singing, other people should be able to search for songs and put them into a play-que after each song the que is being displayed for a few seconds (so people can pass microphones) and the next song in the que is started. initially it would be a small bar at the top of the screen, but eventually this can be extended with multi-monitor support and/or an android app for remote access to the playlist.
i forked a temporarily working copy here: https://github.com/nieknooijens/performous but as with every enhancement, you should at first be able to compile the base program 🎱 .
I already have this set up with the only problem that I get this error at launch:

No config schema file found.
Install the file or define environment variable PERFORMOUS_ROOT

shouldn't be hard to get around but unfortunately I don't know how...

I also had a peek at some code from performous, looks like we have to create a new playlist-editor-screen class, for the actual editing. I also came upon this from screen_songs.cc (I assume this is the song browser):

else if (nav == input::NAV_START) {
ScreenManager* sm = ScreenManager::getSingletonPtr();
Screen* s = sm->getScreen("Sing");
ScreenSing* ss = dynamic_cast<ScreenSing*> (s);
assert(ss);
ss->setSong(m_songs.currentPtr());
sm->activateScreen("Sing");

so I guess [msongs.currentPtr()], returns a pointer for the currently selected song, it shouldn't be too hard to create a linked list with pointers from different songs and check the list after each song.

so will you help me to create this feature?

Hello,

I have to use #videogap option for 2 songs because the mp3 is not ripped from the video file. I discovered Performous does not support this option very well: most of the times the video is not played, only text. I tested with ultrastardx without any problem. Thank you for your help.

Status: There is some framework done i.e. passing the whammy value (the value itself needs some love/interpolating/AnimValue) to audio engine and a dummy function in which to implement the algorithm.

Here is the opinion of Vincent Verfaille (Doctor in Music Technology) when I asked for real time pitch shifter.

Bonjour Vincent,

Le plus simple et efficace me semble être une interpolation de la forme d'onde.
Par exemple, en augmentant le nombre de nouveaux échantillons M générés à partir de N < M échantillons d'origine,
on simule bien la pression sur la whammy bar lorsque le pitch descend; on simule en même temps les changements
de timbres liés au fait que la corde se détend, mais pas ceux des résonances de la caisse qui normalement ne bougent pas.
Cela dit, pour une guitare électrique, on se permet de les oublier.
Donc, l'algorithme le + simple est aussi le plus efficace!

Une interpolation cubique (voir des B-splines cubiques) est adaptée pour cela, elle permet de produire des
variations de phases cubiques et donc des variations de fréquence quadratique, ce qui évite les sauts de fréquence
aux extrémités de l'intervalle.
Il faut cependant filtre passe-bas le signal avant de le ré-échantillonner, pour éviter le repliement du spectre;
la fréquence de coupure de ce passe bas est donc N/M * Fn (Fn: demi-fréquence d'échantillonnage du signal original).
Tout ceci peut se faire en temps réel, avec une latence de quelques échantillons (le nombre d'échantillons pour
une interpolation cubique étant 4).

Après, reste le problème de la longueur du signal puisque sinon, le signal généré est plus long que le
signal de départ. Deux solutions:
- ajout-superposition (overlap-add = OLA): ré-échantillonnage + passe bas -> OLA, et le tour est joué.
Par contre, cela peut générer des problèmes de phase lors de l'OLA, d'où l'utilisation de méthodes
pitch-synchrones (PSOLA). Ça peut rester du temps-réel, mais avec plus de latence... et d'artefacts potentiels.
- sinon, considérer que la "whammy bar" ne va que vers la caisse de la guitare (et le pitch uniquement
vers le bas); dans ce cas, utiliser le signal d'entrée pour générer le signal de sortie comme expliqué
précédemment, puis le moduler en amplitude en fonction du signal d'entrée. Autrement dit, la hauteur
et le timbre sont obtenus par un signal de plus en plus désynchronisé, mais l'amplitude par le signal
réel. C'est une autre bidouille efficace, surtout lorsque le signal s'éteint vite. Dès que le whammy
bar est relâchée, on revient en mode normal.

Voilà, j'espère que ça aidera!
Vous trouverez les codes Matlab de la transposition (pitch-shifting) par ré-échantillonnage et de la
transposition pitch-synchrone dans des livres comme celui d'Udo Zoelzer (Dagitial Audio Effects; les
codes existent en ligne), il fait exactement ce qu'il vous faut.

Bonne chance,

Vincent Verfaille

Will translate this as soon as I have time ([[User:Yoda|Yoda]] 23:34, 25 January 2010 (UTC))

=== Translation from Google translate ===
Hello Vincent,

The simplest and most effective seems to be an interpolation of the waveform.
For example, increasing the number of new samples generated from M N <M samples of origin
well it simulates the pressure on the whammy bar when the pitch goes down, it simulates the same time changes
stamps related to the fact that the rope is relaxed, but not those of the resonances of the body that normally do not move.
However, for an electric guitar, we allow ourselves to forget.
So, the algorithm is the + single most effective!

Cubic interpolation (see B-splines) is adapted to this, it can produce
cubic phase variations and hence quadratic frequency variations, which avoids the frequency hopping
the ends of the interval.
It must, however, low-pass filter the signal before re-sampled to avoid aliasing;
cutoff of this lowpass is N / M * Fn (Fn: half-sampling frequency of original signal).
All this can be done in real time, with a latency of few samples (the number of samples for
cubic interpolation being 4).

Then there remains the problem of the length of the signal because otherwise the signal generated is longer than the
starting signal. Two solutions:

• Add-overlay (overlap-add = OLA): resampling + lowpass -> OLA, and voila.
  By cons, it can cause phase problems at the OLA, hence the use of methods
  pitch-synchronous (PSOLA). It can stay on the real-time, but with more lag ... and potential artifacts.
• Otherwise, consider that the "whammy bar" is only going to fund the guitar (and the only pitch
  down), in which case, use the input signal to generate the output signal as explained
  above, then the amplitude modulated as a function of input signal. In other words, the height
  and tone are achieved by a signal increasingly out of sync, but the amplitude of the signal
  real. This is another hack effective, especially when the signal goes off quickly. Once the whammy
  bar is released, it returns to normal.

Well, I hope it helps!
You will find the Matlab code transposition (pitch-shifting) by re-sampling and
transposition pitch-synchronous in books like Udo Zoelzer (Dagitial Audio Effects; the
codes are available online), it does exactly what you need.

Good luck

Vincent Verfaille

Hi,

i know you prefer people to push commits to the git repository. But as I don't currently have write access, and I'm not sure if my patch is correct, I'm posting it here. Hopefully someone can check it and commit it.

With this patch the current version in the git repository now compiles and runs on Linux Mint Debian Edition.

It is possible to play multiplayer in current performous (of course it gets better when #51 gets done), but it's fun to be able to play online or in your LAN with your friends.
we will be one step closer to add band feature. should we name it Band instead of multiplayer online?

I've tried to add a custom avatar using the wiki page:
https://github.com/performous/performous/wiki/Player-configuration

but it doens't work anymore it have some error parsing the xml file, so it overwrite it so you are loosing all your highscore :( here the error:

Resizing a few times with Win+Left/Right first leads to graphics artifacts (Performous window rendered black) and lost focus and then makes the entire desktop hang so that gnome-shell uses a high percentage of CPU and doesn't render anything. No kidding. Xorg has to be killed in order to restore a functional desktop (possibly killing gnome-shell and starting some other WM might be possible too, in case you had some very important unsaved work open).

Other than that, there are focus loss issues even when Performous is simply started (in maximized windowed mode, as enforced by Gnome Shell). At times I have to Alt+Tab to Performous when it starts even though normally it receives focus automatically.

These are really Gnome bugs but I don't feel like logging onto their bug tracker so here goes, for now at least.

Should they be combined somehow or one of them removed?

Highscore needs to:

• Remember per mic/instrument which player was using it last
• Ask names for the highest ranked people first
• Display more clearly which player is which

Hi folks,

I love performous, you guys rock for making it!

It would be even better if we could have some (optional) microphone feedback. I am "just" talking about mixing the microphone input to the song output.

I'd write it myself but I am pretty clueless in sound processing. If you think it is easy and sombody can point me to where this should be integrated. I can give it a shot myself.

thanks again!

As the title says: some video's play fine (lucky star - AVI -> FFH264 & FFAAC) but some are really choppy (gagnam style AVI - FFODIVX and guus meeuwis which is also AVI - FFH264) they keep in sync but skip a lot of frames every second....

Most of these are not blockers, but annoyances or enhancements. Not in any particular order.

Song browser

1. I don't particularly like the current light blue color of the game and song title
2. Hiscores look somewhat like they are in a temporary position
3. I don't like the default background (black bg with the white performous guy on the right)
4. With light backgrounds, the right side of the song title becomes unreadable
5. Playlist menu needs separate theme from instrument menu and e.g. darker background
6. Playlist menu tooltips are in a bad position and with poor color, should probably just remove
7. Available game modes should be prominently displayed. I already moved them, made bigger and added some glow, but the glow doesn't seem to work very well on light backgrounds
8. I liked the fallback background of moving tiled covers so much that I added some (different) movement to the regular full screen bg images too. This could be improved.

Singing screen

1. Score dialog goes partially out of screen on 16:9 aspect ratio
2. Mic icon and the score seem to overlap a bit
3. Popup menus are rather ugly
4. Add some zooming, panning and fading into static background images?

Players screen

Much work to be done here.

Playlist screen

1. Displaying covers next to the list would be nice, or at least the next song's cover
2. Background could be the next or currently selected song's background

Record webcam video (if available), audio and input event information to be stored with a high score, or allow sharing online.

There are a number of technical difficulties that need to be solved.
-Syncinc audio clocks together for a single audio track that matches the original song
-A/V compression with ffmpeg (realtime in a separate thread?)
-Online features (separate issue)
-Input storage format for instruments and dance (if supported at all)
-Disk storage format (is video stored only once and each player stored separately?)

Cairo uses linear gamma and premultiplied alpha but we handle bitmaps from it as sRGB, causing a few issues. However, simply switching to linear RGB won't solve the problem because Cairo (toy API) PNG loading is broken and it doesn't gamma-correct loaded images. Presumably gdk-imglib PNG loading API might do proper gamma correction but that will cause banding because Cairo only supports 32 bit RGBA (8 bit per component).

Currently, due to Cairo thinking that it is operating in linear space, even though it isn't:

• Premultiplication is done in sRGB instead of linear RGB (where it should be), resulting partially transparent pixels displaying in wrong shade.
• Blending and AA operations produce incorrect results.
• SVG colors might be off even when not transparent (not sure what the specification says or if rsvg handles correction anyway).

Possible fix 1: load PNGs and JPEGs using our own loader that correctly converts them into linear float format. This means a lot of pixel fiddling and potentially slow processing in software. Cairo and other sources could use their native formats without issues when bitmaps are out of the way (although some banding would still occur with Cairo).

Possible fix 2: Use Cairo gdk-imglib loading in hopes that it does things properly. This will cause banding due to the limited precision of Cairo image buffers (gamma-correcting back and forth in 8 bit precision). This is technically the correct way to deal with this but both performance and image quality will suffer.

Possible fix 3: Load images as they are, using our own loader, with no premultiplication, and rewrite rendering code so that it can work with non-premultiplied textures. This gives us the fastest image loading and good image quality but implementing multiple rendering modes might be tricky. Cairo can only be used for text and SVG, and it will still require support for premultiplied linear RGB textures.

All solutions that I can think of are difficult and there are drawbacks. Things mostly work the way they are now but we cannot use e.g. white transparent pixels in images, SVG or text (it will display in gray) and anything that is transparent renders incorrectly.

As a reference, the image sources and their native formats that we have to deal with:

• JPEG (RGB24, sRGB)
• PNG (RGB24 or RGBA32, non-premultiplied, sRGB)
• SVG (BGRA32, premultiplied, linear)
• Text (same as SVG)
• Video (RGB24, sRGB -- but libswscale can do other formats, YUV would be best)
• Webcam (BGR24, sRGB)

When pressing Start during song start (before instrument menu was shown), Performous segfaulted. Party in progress, can't debug-- But registering this here so that it is not forgotten as it is obviously a blocker for 0.8 release.

any suggestions what to do from here? thanks

Add features needed for running Performous in embedded systems such as arcade cabinets.

• Kiosk/arcade mode (disable exiting the game and limit other functions, auto-reset after idle for a certain period)
• Allow playing a single song given as command-line argument (no menus)

We are waiting for a commercial sponsor to pay for the development.

I was trying to find some easy dance in performous, and it seem there is no way to sort, filter, or even look at available difficulties without launching the track. It would be great to have someway to quickly find track whose difficulties match one's capabilities.

Hello,

I just downloaded to try the Guitar hero controller for Android/iOS and the PC server (see https://play.google.com/store/apps/details?id=com.rainy.fretsplayer&hl=es) and it ask me to change the keyboard mapping configuration in order to work.

What it do is to show the frets colors in the phone, and send the respective keyboard keys (1 to 5) But in this controller the pick and the whamy are 6 and 7 respectively. In Performous is shift/enter and backspace, again respectively.

There is no way (that I know) to change the mapping of the app, since is very basic and closed.

I looked in all the xml in both "program files/performous" and "user/app data/roaming/performous". In the IRC they told me to change a file (config-controllers.cc or something like that) and compile. Too much for me.

So, I recommend to add keyboard configuration in next versions, so we can adapt Performous to any kind of initiative like that.

Performous is currently using SDL 1.2. Porting over to the new (soon to be released) version will enable:

• Multiple keyboard support (e.g. more than one keyboard guitar at a time).
• Multiple display support (currently broken because of SDL 1.2 limitations).

Care must be taken to still support SDL 1.2 as well because it will take a while until 2.0 becomes widely available. Because Performous' reliance on SDL facilities is light, supporting both shouldn't be difficult. Porting should be done in branch "sdl2" (not yet created) and the work should only be started after the 0.8 release (scheduled this Friday).

TODO:

• Add FindSDL2.cmake script (find one that already exists or write our own)
• Modify game/CMakeLists.txt to detect/choose a version
• Fix any API incompatibilities in code
• Make use of scancodes rather than keysyms for guitar frets and other things that should use the same key no matter which layout (e.g. French vs. English)
• Implement proper multi-display support (this is a major task)

Note: the current input system already supports multiple keyboards in theory. The keyboard number is just always zero with SDL 1.2. Simply using SDL 2.0 instead of 1.2 should enable this new feature and thus it is not included as a TODO task.

I'm not saving high scores on git from yesterday, anyone confirm?

I've rewritten a large parts of the filename handling of Performous as well as the parts of songparsers dealing with this. The work is nearing completion and I am looking for a merge to master but this needs to be reviewed and tested thoroughly because it will almost certainly create some regressions.

On the positive side, it fixes a number of existing bugs and makes automatic media file finding better than at any point before. And it eliminates a lot of redudant code.

• Songparsers of specific types no longer seek for their media files. This is done centrally in songparser.cc.
• All paths are absolute, so you can refer to song.cover or other files directly instead of song.path + song.cover.

Comments are welcome.

It would be nice if we can collect high-scores from all clients (if they willing to send their score for us).

DLC (Issue #4) make it possible for users to play the same song that server can identify.

when rewinding a song twice really fast, the sound stops and the song continues, when playing a bit around with the song again (forwarding, rewinding) the sound starts playing again.

Easy to reproduce with Guest User.

Start Performous and try to configure for example audio inputs. Saving configuration does not work.

Performous works ok after .config directory manually created to home directory.

One of the menu pics in main menu (the one used when "Perform" is selected) suddenly displayed some CD cover instead of what it should, and would stay that way until the menu was refreshed (by entering Practice in my case). This suggests a bug in threaded texture handling (or graphics drivers, less likely). Could not reproduce.

we already discussed this on IRC, and I already made a new branch but I wanted to share some Ideas:
1 - interface should contain 3 tabs, 1 for viewing the playlist, 1 for managing the playlist and 1 for remote control, I created a mock-up using http://jquerymobile.com/ builder but I can't add new pages to it using the editor, so I think I should go back to text based stuff.

the mock-up is here: http://ubuntuone.com/7mvcjWYXewyM9jWqT9XM5C
2 things to mention that doesn't concern this issue:
1 jquery mobile uses MIT licence, which is compatible with GPL so that's good!
2 the automated build-system http://aave.performous.org/ci/ci.cgi doesn't generate anything good.

We can reduce but not entirely remove dependency on Boost by replacing parts of it with stdlib equivalents. This bug is a tracker for features to replace, and for discussion about compiler compatibility.

• boost/algorithm/string.hpp: No stdlib equivalents
• boost/bind.hpp: std::bind in functional
• boost/circular_buffer.hpp: No stdlib equivalent
• boost/cstdint.hpp: Now in stdlib (cstdint)
• boost/date_time.hpp: Partial support from stdlib (chrono)
• boost/filesystem.hpp: C++ still doesn't know of files :/
• boost/foreach.hpp: C++11 built-in range-based for!
• boost/format.hpp: No direct stdlib equivalent but see std::to_string(num)
• boost/function.hpp: std::function (functional)
• boost/iostreams/stream_buffer.hpp: ???
• boost/lexical_cast.hpp: See std::to_string and std::stoi etc. (string)
• boost/noncopyable.hpp: C++11 deleted functions (but noncopyable is cleaner in code)
• boost/program_options.hpp: Never gonna get into stdlib
• boost/ptr_container/: Not in C++11 and probably not in C++14 either.
• boost/regex.hpp: The last time I tried (quite recently), the libstdc++ implementation was unusably incomplete.
• boost/smart_ptr/scoped_ptr.hpp: std::unique_ptr in memory (also replaces std::auto_ptr)
• boost/smart_ptr/shared_ptr.hpp: std::unique_ptr (if shared_ptr was only used for calling a free function of a C lib), std::shared_ptr if the resource is actually shared, C++11 move semantics instead if a resourse is only being moved.
• boost/thread/: std::thread and stdlib mutexes (no idea if stdlib implementation is good yet or if all necessary lock types are included or not)
• boost/variant.hpp: Didn't make it into C++11

We don't currently use Boost.ASIO directly but likely will, soon. Sockets didn't make it into C++11.

I'm packaging performous into Fedora.

I saw a spec for 0.5: http://gauret.free.fr/fichiers/rpms/fedora/performous/performous.spec

But from the performous docs: https://github.com/performous/performous/wiki/Building-and-installing-from-source#wiki-Fedora

I found something different.

Can you tell me what it exactly requires?

Thanks.

At the end of Iron Maiden - Run To The Hills, when playing the first notes of big rock ending on keyboard guitar, Performous segfaulted.

controllers/info: processing (keyboard 0 instrument 2) GUITAR BLUE (NAV_NONE) value=0
controllers/info: processing (keyboard 0 instrument 2) GUITAR RED (NAV_NONE) value=1

The new rendering engine in 0.7.0 should make this rather straight-forward. Implementing this would allow us to try porting the game to new embedded and mobile platforms such as the Raspberry Pi (which has been requested a few times; performance might become an obstacle but it's worth a try).

Now that's one weird issue.

I mostly use, for now, Performous's "Training" feature (read the microphone's pitch and shows it on a sheet). This tool is useful to me when creating song files with Composer alongside, as seen as in a semi-related issue report on COmposer's GitHub page.

My microphone is actually a throat microphone. This allows me to keep my hands free while working, and minimize external noise impact. However, it tends to over-amplify some sounds, such as coughing , or scratching near the throat; in such cases, Performous tries to analyze the pitch and draw notes on screen, fails, and segfaults.

When launched in a Terminal, the error is reported as:
"terminate called without an active exception"

This might be a hint regarding how Performous handles the microphone inputs. I doubt this could appear in-game, in regular play situation - the input usually isn't that aggressive.

OS: Ubuntu 12.04 64bit
Performous 0.7.0

Used windows version no issues. Grabbed newest git on Ubuntu (duet and videogap support), player one mic is normal, player two mic is always a step high on pitch. I can swap mics to verify its the second usb port rather than the mic. Duplicated on other hardware, same usb mics.
Mics are Audio-Technica USB.
Any ideas?

When I start a song, the first note is skipped every time, this wasn't present before I pulled the last changes from master to webserver, so the culprit is among these lines:

I'm able to reproduce it on both my desktop and my laptop now....

Hello,

I have a SingStar 80's vol. 3 for Nintendo Wii and I would like to know if I can use the files with Performous 0.7? On the DVD, in the songs directory, each karaoke music have .xml (lyrics, tempo...), .tex (cover?) and .vid (vidéo in bink format) files. Is performous could read directly this files or do I have to convert them? If I have to convert them, someone could explain me how? I saw on a tutorial I could convert .vid in avi file with radtools, but I found nothing for the xml and tex files...
Thank you.

I have no idea what this is but it was in the TODO and sounds like Yoda...

After have choose a song, if you press a button in the guitar to select the player you can not move in the menu that appear (the menu to choose the instrument, the difficulty,...) you press down and it immediately go up to play, and also if you green to start the game the menu go away but reappear immediately after, also it seems that the start button create more mess than helping.

Tried with 2 guitar, it works with the keyboard only.

The option flickers between gray and black every frame when a mic is chosen (not for output). Current settings (all mics and output currently not set) do not seem to affect it but the bug doesn't occur every time. I suspect that this might be caused by the settings actually having invalid value other then "not set" because making any setting (pressing Enter) clears the flicker problem.
