What process crashed? systemsettings, or kwin_wayland? Systemsettings: Sun 2024-03-10 16:09:19 ACDT 1745848 1001 1004 SIGSEGV present /home/justin/kde/usr/bin/systemsettings 14.4M Sun 2024-03-10 16:09:20 ACDT 1746099 1001 1004 SIGABRT present /usr/lib64/kf6/drkonqi 806.7K Sun 2024-03-10 16:09:20 ACDT 1746080 1001 1004 SIGABRT present /usr/lib64/kf6/xdg-desktop-portal-kde 983.6K Sun 2024-03-10 16:09:21 ACDT 1746146 1001 1004 SIGABRT present /usr/lib64/kf6/xdg-desktop-portal-kde 981.8K Then immediately after it, drkonqi and then xdg portal To add further context to this. I was changing two settings, screen layout and refresh rate. I tried just today changing the screen layout on it's own and it works fine, no freeze/crash. So the refresh rate change is what causes it. Aha! That's helpful, thanks. Is it 100% reproducible that changing both at once causes a crash, but changing only one at a time does not? Crashes just when applying the refresh rate, have just tested. It freezes for (estimated) 20-30 seconds and then kills the whole session and I'm back at SDDM. Thanks. And it's still happening with the same backtrace? I'm not sure if it's the same but I'll paste it just in case. I'd also just started a kdesrc-build so I cancelled it real quick and one ?? shows up in the backtrace, but hopefully it's still useful.
Also of note, when the crash and session being killed happens, all other apps crash on their way out:
