I haven't been able to reproduce this on Fedora 39 with Plasma 6 stuff built on top of it after 3 reboots. So maybe it's already fixed in Plasma 6. Let's close it for now until we get any reports of it from people on Plasma 6. Thanks anyway for reporting it!

BTW, do you use NVIDIA GPU? This seems to be only reproducible on NVIDIA GPU. I am using NVIDIA Driver version 545.29.02. Ah, I'm not using an NVIDIA GPU. That could indeed be related. Re-opening. Are you able to test the Plasma 6 beta release? (In reply to Nate Graham from comment #3) > Ah, I'm not using an NVIDIA GPU. That could indeed be related. Re-opening. > > Are you able to test the Plasma 6 beta release? I just tried Plasma 6. Plasma 6 does not have this issue (I tried 8 reboots or so). I guess Plasma6 has fixed this issue, so I am okay closing it if we don't plan a backward fix on 5.27.9. However sidenote that there is pretty bad flickering issue across the plasma desktop/wayland applications/X11 applications on NVIDIA card (suspect duplicate of https://bugs.kde.org/show_bug.cgi?id=478563). Yes, I'm afraid no more Plasma 5 releases are planned. Thanks a lot for testing! |

In System Settings/Display and Monitor/Display Configuration - Legacy Applications (X11), select "Scaled by the system", and use Scale factor 200% 2. Restart the machine. (May need to restart several times to reproduce) OBSERVED RESULT kwin_wayland will crash with the above stacktrace. EXPECTED RESULT kwin_wayland does not crash.
