Created attachment 172676 [details] Systemd journal with the stacktrace and everything. SUMMARY I was watching a video on the FreeTube app, then at some point everything went black and got a bunch of windows from different applications telling me that they had crashed (meaning the compositor had crashed). STEPS TO REPRODUCE 1. Open a series of videos on the FreeTube app 2. Wait for the crash OBSERVED RESULT KWin crashed. EXPECTED RESULT KWin should not crash. SOFTWARE/OS VERSIONS KDE Plasma Version: 6.1.4 KDE Frameworks Version: 6.5.0 Qt Version: 6.7.2 ADDITIONAL INFORMATION Fedora KDE 40, kernel 6.10.3-200, a bunch of other apps open like LibreWolf, Firefox, Telegram Desktop, Nheko, QOwnNotes, slow connection (if any of these other details even matter).
Thanks for the bug report, but unfortunately the un-symbolicated stack trace buries in a giant syslog is not very useful. Can you follow the steps at https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl to refine it, and then paste the output here?
Created attachment 172780 [details] Better stacktrace. Uploaded the better stacktrace.
Hmm, I'm afraid that isn't any better. You don't need to use sudo, just do `coredumpctl gdb 2583`. Then when prompted, type `bt`.

Thanks. Unfortunately it's still not very useful, though it's not your fault.
