Comment 2 for bug 760814

I got the same problem on my 8600m GT. It feels like running compiz 0.8x without the --loose-binding option with the NVIDIA driver. Indeed loose-binding has been removed in 0.9x, instead there is an explicit --strict-binding option now.

Nvidia driver versions same as above, also using classic gnome desktop. Upgraded from Maverick a few days ago.
