  [ubuntu 14.04.2] Artefacts in radeon driver on kernel 3.16 and upwards

Status in linux package in Ubuntu:

Bug description:
  Ubuntu-Mate 14.04.2

  This is what I get if I run a kernel newer than 3.13: https://www.youtube.com/watch?v=nx2-Fvihzxg
  sorry for the link, I just don't know how to describe these artefacts verbally.
  (a storm of small horizontal moving blips from right to left ??)

  Those artefacts appear as soon as new kernel is selected in GRUB, and
  remain during the whole session.

  The lastest kernel (from the main repository that is) working without
  artifacts is v3.13.0.59. All later kernels have artifacts. All later
  kernels also are either "-utopic" or "-vivid" instead of "-trusty",
  but I do not know if it is related.

  GPU: Mobility Radeon HD 3200 (RS780M)
  System: Ubuntu Mate 14.04.2  32-bit

  Kernels tested: (and earlier) , , 
  Only (and earlier) are without problems.
