-- Information about the crash:
I have two displays connected to my PC:
1: 1080x1920 BenQ
2: 2560x1080 LG
The LG was connected, but set to a different input. So KWin did not send any
display output to that.
Steps before the crash:
- Have a video playing in Firefox on the BenQ Display
- Switch the LG display to the input coming from the PC
- The 'display connected' sound gets played
- KWin apparently tries to start sending image content to the LG display
- KWin crashed and restarted
Note this crash only rarely happens, most of the time the new display gets
added correctly.
The crash can be reproduced sometimes.
