Bug Description
When waking up the system from a suspend-resume cycle, the display most times shows distorted colours.
As a workaround one can switch to the linux console (VT) and back to fix the display.
Alternatively triggering DPMS also fixes the problem (xset dpms force off ; sleep 0.1; xset dpms force on)

I've tested Ubuntu Xenial (16.04) with the latest updates:
mesa 11.2.0-1ubuntu2.2
xserver-
linux-image-
xserver-xorg-core 2:1.18.3-1ubuntu2.3
I've tried older kernels, xorg, linux-firmware, as a colleague claimed it started for him after some of the latest Ubuntu updates, but couldn't find a working configuration.
I also checked Ubuntu Yakkety (16.10), where I couldn't reproduce with XFCE, but instantly with the Unity session, but probably XFCE was just lucky, as sometimes I also had series of working (~5) cycles. Current versions:
mesa 12.0.3-1ubuntu2
xserver-
linux-image-
xserver-xorg-core 2:1.18.4-1ubuntu6.1
I'm also going to test Trusty (14.04) to check if it's really a regression. At least I have never seen this problem while running it.

This is just a display problem - a snapshot is correct, so it really looks like a radeon driver problem, instead of an xorg problem.
The wrong colors are always different, so every cycle produces a different result. For a photo as background it almost looks like modern art ;-)
