Bug ID: 488713 Summary: kwin_wayland crashes in QCoreApplication::notifyInternal2(QObject*, QEvent*) - multiple times per week Classification: Plasma Product: kwin Version: 6.0.5 Platform: Fedora RPMs OS: Linux Status: REPORTED Severity: crash Priority: NOR Component: wayland-generic Assignee: kwin-bugs-n...@kde.org Reporter: mars+...@montik.net Target Milestone: --- *** If you're not sure this is actually a bug, instead post about it at https://discuss.kde.org If you're reporting a crash, attach a backtrace with debug symbols; see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** SUMMARY Almost every day kwin_wayland crashes for me. I do not know what reproduces it, it happened while I was using the computer, while it was idle, at day, overnight, etc..

STEPS TO REPRODUCE 1. Unknown, but happens too often 2. 3. OBSERVED RESULT kwin_wayland crashes and takes the whole desktop with it. EXPECTED RESULT No crashes.
