Flickering shadow in Phat

[Zoltan]

I have a weird shadow from the ground mesh in Phat:



It disappears and reappears every time the mouse travels a pixel, so it flickers like crazy.

System specs:
XP SP2
Sapphire Radeon 1800XL
Athlon 64 X2 3800+
2 Gb RAM

I've tried several drivers, 7.3, 7.10, 7.10 Omega, 7.11, but it's still the same.

Any idea what's going on?

system specs:

dual Core 2
Xp Sp 2
Radeon 1950 ( Radeon problem? )
