-- Information about the crash:
I have tested my external monitor via a USB-C HDMI adapter and have set the
screen setting to "mirror". It all worked well until I pulled out the USB-C
adapter, after which plasma reliably crashes with the attached stack trace.
The crash can be reproduced every time.
