Addional info to be clear: It seems the issue is really triggered by typing while the animation of "exiting the effect" is happening. Respecting the "animation timings" ( meaning activate effect, wait ... write, wait .... exit, wait will not trigger it ) Cannot reproduce. Can you retrieve kwin's backtrace when it's frozen? You may need another computer to ssh. (In reply to Vlad Zahorodnii from comment #2) > Cannot reproduce. Can you retrieve kwin's backtrace when it's frozen? You > may need another computer to ssh. Can you confirm that you have Overview to the Meta key ?: [ModifierOnlyShortcuts] Meta=org.kde.kglobalaccel,/component/kwin,org.kde.kglobalaccel.Component,invokeShortcut,Overview ? I can confirm that I also didn't manage to trigger it without having Meta as the "launcher" for Overview. But I can with Meta as the overview launcher Where can I upload the coredump ? Its 19M Kwin now, instead of hard locking, just crashes and is being able to restart. ( dunno why, although I did change sddm and updated everything to latest git versions ). backtrace:

Interesting, after building with asan+ubsan locally I get the same crash as on CI https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/2246 fixes the test crash. Probably there's a similar issue in the kwin code I have generated backtrace for bug I reported in 460702, if it helps.
