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.
Actually, sometimes "more activity" makes it go away too. Moving a window around wildly with the mouse makes it *stop* happen.
But moving the mouse over different elements of the screen - or writing text in the web browser email window - seems to make it worse.
Funky.
It does "feel" to me like some bandwidth limitation, it has kind of the same behavior that I remember from the bad old times when you were pushing the video card past a resolution that it could really handle.
But that can't be the case, this card has had no problems with this before.
