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.
