Public bug reported:

After a fresh installation of Lucid Lynx (not via update-manager), I
noticed a huge performance drop in 2d graphics with the nvidia
proprietary driver, compared to karmic.

The whole interface seems unresponsive and slow. Common actions like resizing, hiding or unhiding a window in the panel, displaying a menu, browsing files etc... happen with a delay. 
It is most noticeable with nautilus, files and folders take quite a long time to display.
I thought it was related to the window-manager, but I tried to disable compiz with the same result.

On the other hand, 3d performance seems unaffected by this problem, for instance blender runs smoothly.
I can also play videos, even in full screen, without problem.
It may be worth saying that I tried to use the nouveau driver with *slightly* better results.

My system :
Ubuntu 10.04 LTS x64
nvidia-current 195.36.15-0ubuntu3
HP HDX 18 Laptop
Nvidia Geforce GT 130M video card
