  • 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 ?

        i can't play a full game without crash the oibaf ppa is broken for hon right now.

        it just crashes randomly...

        now i tryed the openGL renderer instead of the directX one now it does not crash.

        means the bug is a wine/directX bug with the radeon driver ..

            it just take longer to crash... is this a VRAM memory leak ?

            HON is broken with oibaf on my hd4770 right now..

            plesse update the ppa

                • r600 LLVM support has improved recently so the bug may also be fixed in git. If not I can disable it. However I cannot build mesa due to a recent bug: https://bugs.freedesktop.org/show_bug.cgi?id=50604 . If it get fixed before friday I'll push a newer mesa, else you should wait until July since I am going on vacation . (I have no time to do other workarounds currently).

                    ok i dist-upgrade again and played 6 minutes alone on a map no crash then i joined a real game with other heroes then the game dit crash...
                    means the bug isn't fixed with the new files from today.

                    some shaders crash the LLVM compiler.. maybe its better to disable it before you go into your vacation...
