-- Information about the crash:
- What I was doing when the application crashed:
I plugged in a new screen via HDMI. That screen should become the new primary screen. When pluggin in plasma crashes and resets the desktop background image on the laptop screen (which was primary, but now became secondary)

The crash can be reproduced every time.
