You have been subscribed to a public bug:
1. boot machine
2. open a terminal and a browser window
3. see that xorg CPU usage is low (< 5%) and always below compiz
4. open 3 more terminals and 3 more browser windows
see that xorg CPU usage is HIGH (somewhere between 30-80%) when window content
is being updated (scroll down on a web page).
when the window content is not being updated xorg still uses ~10% of the CPU.
