Lines blurred like a barcode? Not sure how to describe it but pics included

Hey, so Ive recently reinstalled my version of adobe animate lately for noticing alot of things happening that shouldn't be. I am still getting errors though. I noticed that some little hairs i drew with the classic brush tool did this at some point i (not sure when) Its kind of like when a pic gets corrupted and it looks like someone took sandpaper to it.
