Image differences of "Space Run" using Mesa13 vs AMDGPU-PRO

Image differences of "Space Run" using Mesa13 vs AMDGPU-PRO

Overview:
There are some possible shader issues when comparing screen shots of "Space
Run" with Mesa13 to AMD's AMDGPU-PRO.

Hardware and versions: 
The images were captured Using the Mesa 13.0 branch and AMD's AMDGPU-PRO's
16.30 driver. These image differences were observed on both AMD's Rx470 and R9
Fury graphic cards.

Attached Images:
Attached are the captured images.

--- Comment #1 from Michel Dänzer <michel@daenzer.net> ---
The differences seem very small, not obvious to the naked eye even when
flipping back and forth. Are you sure that

* The difference isn't allowed by the OpenGL specifications
* AMDGPU-PRO is more correct

?
