Description Rafał Miłecki 2009-08-02 13:38:46 UTC 
I was using mesa/drm commit 062c98f4d9264f694ad348baff2babdddccc1ee4 (r6xx-r7xx-3d branch) for some time without problems. Test glxgears was working fine, just little flickering caused by lack of IRQ support.

Then:

    r600: get updated pending age from cs ioctl
    REQUIRES AN UPDATED DRM

introduced corruption to glxgears on my GPU. I documented that on first video. So I updated mesa/drm to commit ee88fe9981dc0120a088c3028caf9e506c95f1c4 but corruption is still here (just little different, see second video).

Also updating mesa to git master doesn't help (third video, I think very similar to second one).

The flickering has nothing to do with irq support.
Comment 3 Alex Deucher 2009-08-02 15:31:27 UTC 
Are you sure you're actually using the latest drm and mesa?  I can't reproduce any regression with glxgears here.
Comment 4 Rafał Miłecki 2009-08-02 23:15:57 UTC 
Huh, I Linux world I've forgotten about thing called reboot. It seems reloading both: drm & radeon modules wasn't enought.

Today I booted again and it works fine.
