Smudge Glitch
I was painting in Photoshop when I had this issue pop up. It pops up when I try to view layers, hide layers, use the paint brush tool, smudge tool, anything. Even auto saving sends my screen and canvas a mess.
I tried to resolve this issue by reverting to an earlier version of the work and it seems the entire file has some form of corruption. I will link images of both the black and white smudges bug over my canvas and the glitched/corrupted file image.
