            Status: NEW
          Severity: normal
          Priority: medium

hi,

i get texture corruption as seen in the attached screenshot when using dri2. 
when running more 3D intensive applications (like say, etracer), the texture
corruption increases resulting in some graphics primitives not being rendered.

this does not happen with DRI1, with DRI1, there is no corruption and all
primitives are rendered as expected.

this is on linux 2.6.38.6 with alpine patches, mesa 7.10.2 and xorg 1.10 with
xf86-video-ati 6.14.1, libdrm 2.4.25 and uclibc 0.9.32-rc3 (also with alpine
patches).

there are some bugs that look similar to what i am seeing, but they are all
marked RESOLVED, and none of them mention DRI2.
