Thumbnails have a default opacity of 0.8 (or the like) and when hovering they fade into full opacity. That definitely requires more than one repaint. I can't see any superfluous repaints when moving the cursor over the new tab page - all I see is the opacity transitions on :hover.

I see multiple repaints, I don't know how many. And I don't know if the number of the repaints I see is more than the necessary or not. One of the repaints happens nearly one second after I move the cursor out of the thumbnail (or above). Feel free to close the bug if there's nothing to do here.
