SUMMARY CS2 crashes when ALT+TABbing, especially when doing so quickly. STEPS TO REPRODUCE 1. Launch CS2 from Steam under Flatpak (not sure if Flatpak is necessary to trigger, probably not) 2. Ensure game is set to Fullscreen or Windowed Fullscreen 3. ALT+TAB a couple of times, the game will freeze, crash or both OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.1.1 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.2 Kernel Version: 6.9.6-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 7600X 6-Core Processor Memory: 62.0 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 4090/PCIe/SSE2 Manufacturer: Gigabyte Technology Co., Ltd. Product Name: X670 AORUS ELITE AX ADDITIONAL INFORMATION Downstream older report on Arch forums - https://bbs.archlinux.org/viewtopic.php?id=290162 This can worked around by setting the game to Windowed (not Windowed Fullscreen), but that triggers another Plasma bug making the panel show over the game - https://bugs.kde.org/show_bug.cgi?id=485100
If an application crashes, that's an application problem. Sorry.
Alright, up we go - https://github.com/ValveSoftware/csgo-osx-linux/issues/3754. But CS2 may not be the only game it happens for - what about games that will simply not receive an update, are they unsupported by kwin under Wayland?
