If the task switcher is open and the window which closes happens to be selected kwin crashes. It survives if the window which closes is not selected so that hunch was on the money. That's a known bug. I fixed it quite recently but I can't recall if the fix was backported to 5.12 branch. In either case, you can work around the bug by just enabling compositing. I backported the fix to 5.12 branch. The fix will be available in 5.12.9, which is released on 9/10/2019. *** This bug has been marked as a duplicate of bug 406784 *** In any case thank you very much for providing me an workaround and pointing me towards a fix! Much appreciated!
