          Priority: medium
            Bug ID: 60802
          Assignee: dri-devel at lists.freedesktop.org
           Summary: Kernel 3.8-rc7 breaks rendering on Radeon (confirmed
                    on Cayman)
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: alexandre.f.demers at gmail.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: DRM/Radeon
           Product: DRI

Since temporary fix for bug 58354, I'm able to test some applications once
again and I've found out some rendering issues. In Unigine Tropics, Unigine
Heaven and under another test that used to be OK (I'll come back with its name
soon, I think it was Amnesia's render test), some textures are not rendered
correctly with kernel 3.8-rc7 (vanilla), but are OK with kernel 3.7.7 from
Archlinux 64. I'm pretty sure an earlier 3.8-rcX was rendering OK with the
"still unamed" application.

I'm testing with latest mesa and drm on a XFX HD6950.

I'll try to bisect it later.
