Comment 33 for bug 973506

The bug sure seemed like an nVidia issue to me, especially with the older GPU 8400M GS I have. I didn't even have Firefox running. Switching between windows, moving windows, operating menus produced huge large spikes in CPU utilization. I have since switched to the Ubuntu-x-swat PPA as the source of my nVidia drivers and performance is much better. It still feels more laggy than it should, but it is usable now. I am still running 12.04.
