--- Comment #13 from Chris Rankin rankincj@googlemail.com 2010-08-02 17:25:43 PDT --- I have just upgraded this machine from 2.6.33.6 to 2.6.34.2 and have discovered that the texture corruption is now *massively* reduced. There are still artifacts here and there if I look closely, but the large blocks of mangled textures have gone!
Switching back to 2.6.33.6 makes the corruption reappear.
I'm stunned. I should probably also mention now that I am using KMS.
