Nope. With a single monitor everything seems to look fine. And when I plug in the second monitor, it immediately starts happening again. It also seems to depend a bit on the screen contents - or possibly on what else is going on. Hiding the browser window makes it happen less, I think. But I suspect that's about "less gpu activity" than anything else. I'll see if I can bisect it at least partially. Linus
