• Configuration File:

  • Default configuration file.

• Description:

  • Making a window fullscreen (Super + F) will stop the screen from rendering anything on that workspace until fullscreen is removed (Super + F again). The window itself still works (I can still type into a "frozen" terminal, and I can hear audio on a fullscreen video player), but the visual updates won't show until fullscreen is removed. This issue is not present on sway 1.9. Also, I think it's worth noting that it never actually goes into fullscreen (I can still see waybar sections on the screen).

Turns out that this is only happening on external monitor (this is a laptop, and monitor is connected through a mini-DP to DP cable). Changed title of this issue.

Does it work with the GLES2 renderer?

Just tried with WLR_RENDERER=gles2 and it still happens, but I get this instead:

I also just realized that it seems to be app dependent (with both vulkan and GLES2), since I tried using Firefox and noticed that I was able to make it go fullscreen. I tested with some of the apps that I have installed in case that helps.

• Some apps that work: Firefox, Chromium (with --ozone-platform-hint=auto), Thunderbird, lapce, OBS Studio.
• Some apps that don't work: VLC media player, FileZilla, GIMP Nightly, qBitorrent, Nyxt browser, LibreOffice Suite, FreeCAD, Alacritty.

Something really strange that I noticed while testing these apps is that if I have OBS Studio open and capturing the display, all of the apps will magically start working in fullscreen. Not sure what's the relation but it seems like I can straight up work around the issue by just having OBS Studio open, and the errors don't show up in the logs anymore. Instead, I get these 4 lines being spammed in the log while OBS is capturing the display:
