-- Information about the crash:
This morning I noticed that desktop icons were missing (probably caused by
multiple KWin and Plasma restarts yesterday). I pressed Meta+S – shortcut for
"Show Desktop Grid" effect and then a KWin crash was reported.
I am using a laptop in clamshell mode with external monitor. Laptop resolution
is 1920x1080, the resolution of the external monitor is 2560x1440.
The crash does not seem to be reproducible.
