Title:
  Ubuntu 13.10 Radeon HD 8470D screen flickering and tearing

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  After an upgrade from Ubuntu 13.04 to 13.10,  my unity desktop is
  experiencing screen flickering and what appears to be some screen
  tearing.  Tearing may not be the correct term.  I see random
  triangular areas of the screen which display what appears to be a gray
  scale gradient.  They are not always at the same position. The size
  and position change frequently.  Also, icons are flashing in the tray
  panel a the top of the screen.

  I have attempted to load the propitiatory AMD/ATI drivers, but that
  only leaves me with a black screen after reboot.

  I searched Launchpad and found Bug #1249468 which sounds to be the
  same issue.
