Created attachment 166732 [details] output of journalctl SUMMARY Kwin randomly crashed during regular use. STEPS TO REPRODUCE Unknown OBSERVED RESULT Kwin crashed, the attached log is the output or `journalctl`, trimmed to the relevant parts. EXPECTED RESULT No crash SOFTWARE/OS VERSIONS Linux: 6.7.8-zen1-1-zen (64-bit) KDE Plasma Version: 6.0.1 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 ADDITIONAL INFORMATION
Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols that we need to figure out exactly what's going wrong. 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!

I believe I did; I ran `gdb /usr/lib/libkwin.so.6` and let debuginfod download the symbols, then I can `coredumpctl gdb <id>` and posted the output of `bt`, just like the guides said, or did I need to do it differently?
