Bug 507804

Application: kwin_x11 (6.4.3)

ApplicationNotResponding [ANR]: false
Qt Version: 6.9.1
Frameworks Version: 6.16.0
Operating System: Linux 6.15.8-200.fc42.x86_64 x86_64
Windowing System: X11
Distribution: "Fedora Linux 42 (KDE Plasma Desktop Edition)"
DrKonqi: 6.4.3 [CoredumpBackend]

-- Information about the crash:
Whenever i start a game in lutris using the proton (or wine) runner kwin crashes when the application starts.

The game starts fine, but if i alt-tab back out and into the game again, kwin crashes again and sometimes it can be difficult to get back in the game because it seems like kwin restarting after crashing pulls focus so it kinda flickers back and forth.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
