--- Comment #4 from Andreas Hartmetz <ahartm...@gmail.com> ---
I get a similar backtrace (at least the same failed assertion) after running
zdoom (a Doom engine) with unredirection in full screen enabled. After exiting
the game, the window decorations (shadows?) flicker and look very glitchy. kwin
will usually crash in less than a minute in that state. If I run kwin_x11
--replace, the old instance crashes during exit. I have a backtrace of that:
Application: KWin (kwin_x11), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
