There's no stuttering or other visual artifacts following, in fact everything around the affected areas is fine and nothing else about the game will be abnormal. It also does not seem to correspond at all to level data, it ignores linedefs and sectors, and the linedefs and sectors appear to be perfectly normal if examined, nothing weird with the nodes or visplanes from what I can tell, and these things are always fine in PrBoom+.
I'd be terrified of it being a hardware problem, but the fact I don't experience this with anything else makes me think that it isn't. It seems to just happen on some levels, and I'm not sure why, but it would seem to be something on GzDoom's end. Seems to happen with or without gameplay mods.

My autoload.
The folder still says 3.1.0, because I installed GzDoom 4.5.0 separately, as I wasn't sure if it would work or not (but other than this one thing, which may or may not be 4.5.0's fault, it actually works better overall and I like the new options).[doom.Autoload]

I just dump whatever .wads I download, play, or work on in the old folder, because I'm a computer slob and don't organize that well. Keeps the new folder more tidy anyway.
I didn't see any mention of anything like this elsewhere, but I apologize if this is something that hasn't been reported (I don't know what I'm looking at, mind). I'm not sure if there's further information I can provide.
