Santeri,

We are sorry that we do not always have the capacity to review all
reported bugs in a timely manner. You reported this bug some time ago
and there have been many changes in Ubuntu since that time.

Can this bug report now be closed or do you still see a problem related

Title:
  Scrolling takes huge amount CPU

Status in X.Org X server:
  New
Status in firefox package in Ubuntu:
  Incomplete

Bug description:
  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.
  Scrolling even a light web site using ATI open drivers on Ubuntu 10.10 eats 
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.
