I'm experiencing it as well on Asus UL30VT (GMA 4500HD & Nvidia G210M, Nvidia being turned off). Everything works OK when I turn off Compiz.
Although both video and 3D work ok, these glitches are much more annoying then they seem at first sight. I'm really looking forward seeing this fixed soon. -- [gm45] Glitches appears sometimes on screen.
