Strange glitch/pixelation randomly appearing, then clears when I scroll past the error.

Randomly when I'm working in Illustrator, the program glitches out and becomes weirdly glitchy...then, once I scroll past the issue, the pixelation goes away.

Just wondering if this is an issue other people are experiencing, or if there's an Adobe-centric solve here...or if it's something wrong with my computer. It's definitely annoying as there is no particular process that sets it off - and it slows down my work.
