Title:
  [amdgpu] Severe screen corruption

Status in xorg package in Ubuntu:
  New

Bug description:
  Screen occasionally shows strange distortions and corruptions during almost 
any activity. Static or bars of colour appear in unusual places along the 
screen.
  Corruptions are often (though not always) removed in some sections of the 
screen by the appearance of other display elements (windows, tooltip, 
mouse-over, etc.)
