graphical glitches since last update (LLVM for r600)
First, thank you oibaf for your excellent work about packaging those drivers to provide an easy to use ppa.
I'm using it for several month now with an AMD radeon HD 6950 (2GB). I can play lots of games with good fps (even unigine oil rush is running fine in medium details in 1920x1200).
But, unfortunately, since the last update (where mesa in the ppa uses llvm for r600), I encounter severe graphical glitches for every 3D application (2D desktop and videos are fine).
Here is a screenshot of glxgears :
I'm currently using ubuntu 12.04 64bit, unity 2D. Below are some glxinfo :
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD CAYMAN
OpenGL version string: 2.1 Mesa 8.1-devel (git-6404095 precise-oibaf-ppa)
OpenGL shading language version string: 1.30
I tried to revert to original distribution packages, wich solve the rendering problem, but cause performance and compatibility problems of course...
So I brought back the ppa and the faulty rendering is still here.
Have you got an idea to diagnose this problem ?
