SUMMARY
Hey,

I might have found a bug which happened before, but I didnt know why. At least
I didnt pay attention.

I had mpv with a movie in fullscreen paused, the system went to login screen as
I was afk for a while, when I logged back, it was as if the screen was not the
one and only had the lowest resolution available.

STEPS TO REPRODUCE
1. Have mpv open with a video in fullscreen
2. Let it enter afk mode
3. Log back in

I cant 100% confirm this though.

OBSERVED RESULT
Unusable display with lowest resolution

EXPECTED RESULT
To continue working.
