The black windows with the tiny game window inside

SUMMARY

Hi!

After updating from KDE 6.4 to 6.5, one game of my Steam library has regressed. 

Painkiller Black Edition now only render inside of a black window on the top left of my monitor, inside an even tinier window. 

Before the 6.5 update the game was working nice using the Wayland backend on Proton (using the launch option on Steam PROTON_ENABLE_WAYLAND=1 PROTON_ENABLE_HDR=1) but now this bug manifest itself and if you try to manually change to any resolution, the game crashes closing the window. I've also tried without the Steam options but no luck.

Initially i thought that it was a regression on ProtonGE > 10.24 but using the latest known working version (10.22), the bug still happens, so it might be related to KDE 6.5?

I'd like to add more logs if you need, just ask! 

Thanks for all the amazing work on KDE!

STEPS TO REPRODUCE
1. Launch the game with ProtonGE 10.22/10.23/10.24/10.25
2. The game launch on a black window on the top left of my monitor (see screenshot)

OBSERVED RESULT

There is a black window on the top left of my desktop with inside a tiny window with the game.

EXPECTED RESULT

Fullscreen game

It might be related to https://bugs.kde.org/show_bug.cgi?id=501505 i'll keep an eye on it and test when the MR will be merged :)

Comment 3 Leonardo 2025-12-15 16:15:38 UTC

I've updated to Plasma 6.5.4 and Proton-GE 10-26 and seem fixed.

Comment 4 Leonardo 2025-12-17 06:55:19 UTC

Too soon...still the same problem with Plasma 6.5.4 and Proton-GE 10-26. I gladly gift the game for debugging if needed :)
