On fullscreen, rendering freezes when NVIDIA GeForce Experience is used about panda3d HOT 7 CLOSED

I found more precise conditions.
Window freezes when any overlay is notified by GeForce Experience.
If the notifications is off, the freezing does not happen although "In-Game Overlay" option is ON.
However, if the overlay is opened by shortcut (Alt+Z), the window becomes freezing.

I performed some tests in GLFW App. I pressed ALT+Z key to open the overlay, then window proc message was presented as follow:

WM_SYSKEYDOWN (wParam: VK_MENU)
WM_KEYUP (wParam: VK_MENU)
WM_KEYUP (wParam: Z)
WM_KEYUP (wParam: VK_LMENU)
WM_NCHITTEST
WM_SETCURSOR
WM_NULL
// then, overlay opens.

And the window style and extended window style were not changed.
However, in Panda3D, "ChangeDisplaySettings failed to restore Windowed mode" warning message was printed when the key is pressed.
I guess that the crash happens because of minimizing window by losing focus.

Curious.

Could you include the sequence of events in the Panda window, by setting notify-level-windisplay spam ?

I attached the log file: panda3d.log

I started app with fullscreen #t and win-size 800 600.
(Note that the app is Panda3D C++, not Python.)
After Line 700, alt key and z key were pressed. In Line 771, the warning message was printed.

I checked the issue is resolved in 0edac2e. Thank you!

However, in Panda3D Render Pipeline, the issue still happens.
I could solve it by removing color-bits 0 config OR adding reqs._property[FBP_color_bits] == 0 condition into the commit.
I don't know whether color-bits 0 is meaningless, or reqs._property[FBP_color_bits] == 0 condition is omitted.

Wow, are you sure? I was trying to fix a completely different issue; I'm surprised it seemed to fix this one as well.

I didn't realise the framebuffer properties behaved differently when 0 bits were requested. I've just included that in the condition.

Please close this issue if you can no longer reproduce it with the latest changes, thanks!

I also had another issue that the screen is washed out on full screen, but I thought it was not related to this issue. However, the commit resolved both washed out issue and this issue.

Now, the problem does not happen. NVIDIA overlay and recording works well. Thanks again!
