** Description changed:

  Running Lucid Alpha with todays updates I have some interesting visual
  effects:
  
  Zooming in with Super+Scroll causes the screen to become very dark. It
  looks like the backlight on the display turns off, but I'm not sure.
  Adjusting Fn+Brightness doesn't fix this, although I can tell the
  brightness changing slightly. The same thing happens when changing
  workspaces (Ctrl+Alt+-> or Ctrl+Alt+<-), dragging a window from one
  workspace to another, or using Expo (Super+E) to view all workspaces
  simultaneously. Returning to normal zoom level will always restore the
  correct level of brightness, corresponding to how it might have been
  adjusted during black out.
  
  I'm reporting this against the kernel and not the display driver because
  the bug doesn't appear with the corresponding mainline kernel release
  (2.6.32.9).
