@nikolaof I am moving this issue to #4248 as the current issue is closed and you have a valid - if less than ideal - workaround.

totaam commented on July 22, 2024

Likely fixed in 6.0.1, which has been released

nikolaof commented on July 22, 2024

Hey, I'm trying to update the arch linux package, but for some reason the new release is not listed under https://www.xpra.org/src/. Is there any reason for that?

from xpra.

totaam commented on July 22, 2024

@nikolaof there is, I forgot! (it's just a copy of the one from pypi)
Done now.

I am closing this ticket as a duplicate of #4201 (comment)

Feel free to re-open if you can reproduce with 6.0.1

nikolaof commented on July 22, 2024

Ok. After updating, seems to be better but not perfect. The lines are fine when scrolling but still for some reason I'm experiencing some color changing when moving the mouse around the window.

for example the code panel in the image switch from darker to lighter and vice versa. Somthing like flickering.

totaam commented on July 22, 2024

That's likely to be a colourspace issue (#3837), but I have no idea which codecs Arch enables.
Having the server's -d compress output corresponding to the problematic screen updates would help us narrow it down. (also knowing whether the window uses opengl rendering or not - and whether using --opengl=no / --opengl=force changes anything).

Enabling debug for compress I'm getting a huge such a list. Personally I cannot debug this :) What should we look for? I mean how the distortions/flickering will look like ?

Also, I tried to use both of the --opengl flags you mentioned in the client side and didn't change anything.

totaam commented on July 22, 2024

These 912x955 pixel screen updates seem to be updating almost the entire window since 'window-size': (960, 1059)
Every single one of them is using webp with the exact same key settings: 'quality': 69, 'speed': 33
Except for this one which is the auto-refresh:

options={'optimize': False, 'auto_refresh': True, 'quality': 100, 'speed': 50, ... 'alpha': False, 'content-type': 'browser', 'window-size': (960, 1059)}

My guess is that xpra should be sending only lossless screen updates, but it is sending lossy subsampled (YUV420P) screen updates instead because your application is detected as: 'content-type': 'browser' - for whatever reason.
Raising the min-quality is a bad workaround (a band aid that will affect all applications), a better one is to ensure that your application is correctly detected as text content type.

nikolaof commented on July 22, 2024

Is there a way to modify how the application is detected? I mean the actual application is the Visual Studio Code. As far as I know is based on web technologies like electron. Maybe it makes sense that it detects it as web browser.

That should have worked.
This is where we update the content-type attribute:

xpra/xpra/x11/models/base.py

Lines 452 to 476 in ed358ea

    
           def _content_type_related_property_change(self, *_args) -> None: 
        
               self._update_content_type()

           def _update_content_type(self) -> None: 
        
               # watch for changes to properties that are used to derive the content-type: 
        
               content_type = self.prop_get("_XPRA_CONTENT_TYPE", "latin1", True) or "" 
        
               # the _XPRA_CONTENT_TYPE property takes precedence 
        
               if not content_type and GUESS_CONTENT: 
        
                   # guess_content_type can take a while as it will load the xdg menu data 
        
                   # so call it as a work item. 
        
                   # multiple callers can be added to the sequential work queue, 
        
                   # the menu loader also has a lock. 
        
                   add_work_item(self.guess_content_type) 
        
               metalog("_update_content_type() %s", content_type) 
        
               self._updateprop("content-type", content_type) 
        
           def guess_content_type(self) -> None: 
        
               content_type = guess_content_type(self) 
        
               if not content_type and self.is_tray(): 
        
                   content_type = "picture" 
        
               metalog(f"guess_content_type() {content_type=}") 
        
               self._updateprop("content-type", content_type)

And this should end up calling: guess_content_type

The server debug switch for this module is -d util+window.
This is what I see for --start=xterm:

_load_dict_file()
guess_content_type_from_defs(WindowModel(400012)) prop(role)=None
guess_content_type_from_defs(WindowModel(400012)) prop(title)=antoine@fedora:~/projects/xpra
guess_content_type_from_defs(WindowModel(400012)) prop(class-instance)=('xterm', 'XTerm')
guess_content_type(WindowModel(400012)) found match: property=class-instance, regex=xterm, content-type=text

Seems that it doesn't see any window class or title as it does in xterm example of yours.

Got it:

guess_content_type(WindowModel(400004)) found match: property=role, regex=browser, content-type=browser

It stops as soon as it finds a match, and your application sets the window role to browser-window which matches browser.
You should be able to temporarily workaround this by renaming /etc/xpra/content-type/10_role.conf to /etc/xpra/content-type/99_role.conf so that it is processed after the other ones which you have modified.

Another workaround would be to remove this line:

xpra/fs/etc/xpra/content-type/10_role.conf

Line 12 in 2178dd8

role:browser=browser

I am reasonably confident that the two commits above are correct.
Please confirm that this works for you so that I can backport this to the stable branches.

nikolaof commented on July 22, 2024

To me seems that still identifies it as browser

So what make it work properly was to change your fallback file into smth like

################################################################################
# since this file will be parsed late,
# we can include more generic patterns here:

role:browser=text

But obviously this is not correct

Yes, I realized later on that f0431b1 was wrong: the files are all loaded and placed in the same data structure, so the later files can only override previous settings.
The matching order is not determined by the order of the files.
Let me think about this one.
