            Bug ID: 89699
           Summary: Regression in 10.5.1 causes flickering/artifacting in
                    a particular video game
           Product: Mesa
           Version: 10.5
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Other
          Assignee: mesa-dev at lists.freedesktop.org

Alright so, before upgrading to 10.5.1 I was on 10.4.6 and a game I play a lot,
Counter Strike GO (Available on Steam) was running just fine at good
performance with nothing weird coming up on screen. After updating on 10.5.1 I
am getting lots of white flickering on certain parts of the game (walls or
objects) as well as lines that go accross objects. It appears almost as if it
is GPU artifacting, although it is not because Minecraft and other games do not
produce any of these weird effects.

What can do be done to solve the issue? CSGO is a proprietary game although
Valve is pretty good at giving support for Linux I would assume so maybe some
things can be done. I have no clue what kind of log output would be helpful, I
would assume dmesg and Xorg.0.log yes? I will be adding them in shortly. 

Specs
AMD 7950 3GB 
Arch Linux 3.19.2 kernel
