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).
