odd gfx bug

[Cylian]

upgraded to an nVidia 7900GT, 84.21 drivers, and since I got the card installed there's a oddity when I move a window over the daoc window.
What happens is, that there seems to be a frame stored in the background which gets displayed when another window is put above the one that is rendered.
In the screenie, the upper part is "live" and moving, the lower static like a screenshot.
Otherwise everything works fine, only DAoC shows this behaviour.

Any idea what's causing this ?

Have you tried newer drivers, mine used to do that until I did.. newer being beta that is

newest are the 84.25 and those behave the same way. Can't downgrade because those drivers don't support the card

another oddity is, when I drag the daoc window on the secondary monitor, this bug doesn't appear either.
