backtrace

kwin crashes “sometimes” after changing the monitor settings including:
* disable second Monitor
* switching to clone mode
* changing the relative position of monitors

My desktop effects are turned on.

I could not really find out how to reproduce it deterministically, but it
happens again and again.

This is the downstream bug report:
https://bugs.kde.org/show_bug.cgi?id=299333

I'm on openSUSE Factory at the moment, but it also happened on 12.2.

Please note if you need any more information if you are not able to reproduce
it yourselves.
