Created attachment 162946 [details] Journal logs (including stack trace) SUMMARY I've had this happen twice now, a couple of weeks apart. All of a sudden my displays go black, and a few seconds later the desktop reappear but all my applications have been terminated. Stack trace is attached. Looking in the logs I can see that kwin_wayland has segfaulted. STEPS TO REPRODUCE - No idea, it seems to occur randomly. OBSERVED RESULT Crashes EXPECTED RESULT Should not crash SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.27.9 KDE Frameworks Version: 5.111.0 Qt Version: 5.15.11 ADDITIONAL INFORMATION Kernel 6.5.9 Platform: Wayland I am using bismuth to add tiling functionality to plasma, not sure if this is related.
Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols. Could you please install debug symbols and attach a new symbolicated backtrace generated by using coredumpctl gdb in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this. Thanks again!

As I have no way to reproduce this issue I followed the instructions for using coredumpctl - this is all it gave me. It seems like the dump has now been erased from my machine so I'll have to wait until the problem reoccurs.
Created attachment 163232 [details] All threads stacktrace
Ok the issue has reoccured. I tried to use coredumpctl to take a stacktrace of all threads but I'm still not seeing anything kwin related?

Yeah there doesn't seem to be anything kwin related. But your first stacktrace without the debug symbols does have kwin_related stuff..
I'm not really sure what to do at this point. Would uploading the core dump help?
