I used to have this problem too, but, strictly speaking, I can no longer confirm it because I had to switch Compiz off after the latest updates because it no longer draws window decorations.
Anyway, here is the requested information for my card:
tawmas@tylke:~$ lspci -n | grep 300 01:00.0 0300: 10de:0421 (rev a1)
tawmas@tylke:~$ lspci | grep VGA 01:00.0 VGA compatible controller: nVidia Corporation GeForce 8500 GT (rev a1)
