There are a few near duplicates of this bug, showing up as flashing elements, or with Google docs like the image above. I also had it during scrolling start and stop depending on the visibility of an element on the page. Anecdotally, for me, it needs a couple of hours of usage before it starts happening.
Andrew was seeing in on slack today.
