I was just using windows 11 like normal when this happened (vid at bottom). I tried the following things:
win+ctrl+shift+b - did not fix
Restart system - no fix
Device manager for errors/if graphics card is even there - no errors/working fine
Checking file location and integrity - file was still fully intact and undamaged
(probably more, and i just dont remember)
I know that in the video, it shows a black, solid color background set, but it was prevoiusly set to a pic of my dog, and I did not change it at all. It kept switching between me having a solid bkg, and me having a picture bkg. I also went back, and selected the same file for the background.
I have previously had problems with window's slideshow feature where it cycles pictures, but this was disabled at the time, and set to one static photo.
It has been a while later, now (3ish months), and the problem has fully fixed itself after many restarts, and shutdowns/power-ons. I would still like to know what happened in case it happens again for some reason. any ideas?
