Is this a problem in the Wayland or X11 session? What GPU are you using? Have you tried downgrading only KWin? That would make clear that this is due to a change in KWin rather than some other package/library. If you are able to determine reliable means of reproducing this, that would be quite helpful.

As of the latest update on Arch Linux (and switched to nvidia-580xx-dkms), I'm not able to reproduce the issue anymore. I'll update this report once I can figure out how to reproduce it. And just got a crash.. I'll be downgrading to kwin 6.5.3 and see if the issue happens there.

If anyone knows an NVIDIA engineer, let me know what these ESR means. Created attachment 187848 [details]

Created attachment 187798 [details] journalctl SUMMARY With Plasma 6.5.4, Kwin would do an illegal read operation on the Task Switcher, causing the GPU driver to crash. STEPS TO REPRODUCE 1. Set Task Switcher type to "Thumbnail Grid" 2. Repeatedly bring up the Task Switcher via Alt - Tab 3. There's a chance the GPU driver would crash OBSERVED RESULT Task switcher would work most of the time. EXPECTED RESULT Task switcher causes the GPU driver to sometimes crash. SOFTWARE/OS VERSIONS KDE Plasma Version: 6.5.4 KDE Frameworks Version: 6.21.0 Qt Version: 6.10.1 NVIDIA Version: 580.119.02 ADDITIONAL INFORMATION Doesn't seem to happen with 6.5.3. I have tried to downgrade NVIDIA driver to 580.105 (the last version I was on before rebooting) and the issue still persists. Switching Task Switcher style to "Large Icons" or "Compact" seems to have made the issue go away, as that doesn't display the app overview.
