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.
