Title:
  external monitor flicker in radeon driver on RV710/M92 [Mobility
  Radeon HD 4530/4570/545v]

Status in “xserver-xorg-video-ati” package in Ubuntu:
  Confirmed

Bug description:
  When using Compiz/Unity at my external monitor's full resolution
  (1920x1080), my external display displays horizontal distortion.
  Sometimes the vertical alignment will also waver.

  This doesn't appear using metacity, so it's not a hardware issue. This
  also doesn't appear using the next highest resolution (1680x1050).

  I'm using the radeon open-source driver.
