Bug Description
I have an issue since about a week or so, the display blinks black, like it's turning off and on again. The black blink lasts for not more than a second. I haven't managed to reproduce it in UEFI yet, so i believe it might not be a hardware issue.

1. Does the problem only happen in Wayland, or only happen in Xorg sessions?
2. Next time blinking occurs please immediately open a Terminal window and run:
journalctl -b0 > journal.txt
and attach the resulting text file here.
