-- Information about the crash:
- What I was doing when the application crashed:
  I was downloading texlive and played music from amazon music.
- Unusual behavior I noticed:
  Bevor the crash i cant see my backgroundimage, it was black and the right mouse button do not work.
- Custom settings of the application:
  My setup is an Thinkpad X390 with an eGPU (AMD RX570) via Thunderbold, with two external Displays. The black backgroundimage is very often to notice.

The crash can be reproduced sometimes.
