Title:
  xorg uses too much cpu when many windows are open

Status in nvidia-graphics-drivers package in Ubuntu:
  Invalid

Bug description:
  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.
