Desktop Effects Problems

I am having a problem with desktop effects in openSUSE 11.1. Whenever I enable Desktop Effects, after using for a few minutes, my laptop becomes unstable. The first indicator that it is becoming unstable is when I open the Computer menu at the bottom of Gnome, and I start hovering over the icons in the menu. By default, whenever you hover over the icons in the menu, the icons are supposed to highlight, and when you move the mouse off of the icon, the highlight disappears. Well, with desktop effects enabled, the highlight never disappears. Soon after this, X will eventually freeze all together. I have updated the kernel using the YaST online update, and have also installed the newest nVidia drivers for openSUSE x64 using YaST.

Any help would be appreciated. Thank you.

I think I may have fixed the problem. Apparently the compiz-fusion that comes with openSUSE 11.1 is very buggy, so I followed this guide:

CyberOrg ยป Compiz on openSUSE 11.1

to update compiz-fusion to a newer version. I have been using desktop effects for several minutes now, and the problems I had do not appear anymore.
