I am not sure whether this bug is related to my issue, but I am also not sure how I could figure it out.
Since today I get a white screen on the X display when using an external display and switching from screen mirroring to split screens. Switching to console shows a drm intel_disable_transcoder failure. After reboot the problem occurs reproducible each time screen properties are changed from mirror to split screen.
