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.

I suspect this is fixed now. Reopen if not.
