I'm not sure how kwin could cause that crash, unless it's a bug in the batch renderer itself. *** Bug 445677 has been marked as a duplicate of this bug. *** A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/1791 Git commit 64f2cdf9ed290a1fb7c2bf41753613078eb023c4 by Vlad Zahorodnii. Committed on 13/12/2021 at 13:29. Pushed by vladz into branch 'master'. Fix memory leak in some plasma components A few plasma components cache QSGTexture. Those components rely on texture references going away with QSGNode users. However, with the current tear down logic, OffscreenQuickView won't destroy any paint nodes. Destroy QQuickRenderControl before QQuickWindow to ensure that are no paint nodes left alive after OffscreenQuickView.

Created attachment 142866 [details] backtrace SUMMARY I have verified the crash on archlinux and Neon. I've got a backtrace with symbols from the latter. STEPS TO REPRODUCE 1. Enable the new overview effect. 2. Enter overview. -- Entering and exiting overview rapidly will certainly cause a crash sooner or later. You can use either the shortcut or a hot corner, but I used a hot corner to get the backtrace.
