And FWIW I've periodically seen this crash on Plasma 5 too; removing the qt6 keyword. Just figured out the reproducer, hence the bug report.

STEPS TO REPRODUCE 1. Hover the cursor over a window decoration button so that its tooltip appears 2. Quickly move the cursor over to it and click on the tooltip (generally this isn't something you do on purpose, but it can happen by accident) OBSERVED RESULT Some of the time, kwin_wayland crashes. EXPECTED RESULT No crash.
