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.
