I had the same problem with my old video card (Geforce 3 Titanium).
...and I steel have this problem with my new one (Geforce 6800 GT), but with not all the visualizations.
And I am a geek for video stuff, so I have installed all new drivers.
...err... I don't want to be nasty, but Visualizations are not very beautiful : this is the only thing that I don't like in MC..

3D vis are better, but the viewport is not correctly resized in window mode.

Moreover, the cover art vis don't resize the picture to fit all the area
