Scrolling takes huge amount CPU
Status in X.Org X server:
Incomplete
Status in firefox package in Ubuntu:

Binary package hint: firefox
Web browser is hitting a software fallback in the X server, but the browser
process is still using more CPU than X.

huge amount of CPU. Proprietary drivers gives same results. Tested with
Firefox 3.6-4.1 and Google Chrome.
Graphics card is ATI Radeon 3470.
Laptop: Toshiba Satelite A300
Excepted: Scrolling is smooth
Happened: Scrolling lags and eats huge amount of CPU.
