Steam app 1091500 playing window not shown after using workspace switcher in Ubuntu

[CaptainMorgan12]

Environment:
Ubuntu 24.10 beta Ubuntu Oracular Oriole (development branch), Apple Inc. MacPro7,1, Intel® Xeon® W-3223 × 16, AMD Radeon™ 2 x Radeon RX 6800 XT, Custom kernel for the MacPro Linux 6.11.0-1-t2-noble (so the fans work), Wayland 1.36-1, Mutter 47.0-1ubuntu2, mesa-vulkan-drivers 24.3git2409221842.fd11bboibaf~n, Steam Version: 1726604483, Proton 9.0-3, Cyberpunk 2077 (or any other steam game), Display 3840x2160, Fraction Scaling On 150%, Refresh Rate 144Hz (Fixed).

Steps to repeat:

1. launch game with proton compatibility mode cyberpunk 2077 in my case
2. launch option "-fullscreen"
3. observe game launches in fullscreen window
4. use workspace switcher and switch to a workspace to the left or right of the steam app window that is running the game
5. switch back to the steam app window

Observe steam app window shown in workspace switcher, but shows nothing once switched to the steam app window.

Workaround:

1. launch option -windowed
2. launch option -fullscreen and do not switch to another window using workspace switcher

With the smaller windowed steam app window when switching work spaces and then back to the steam app window it does not disappear. However, this is not an ideal window configuration since I would like to play using my entire screen.

Hello @CaptainMorgan12, we're tracking issues with games run with Proton in the Proton issue tracker. Also, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to ValveSoftware/Proton#4450 (comment).
