ut2004 screenshot illustrating the texture rendering issue

Hello,

I noticed a regression in the mesa i965 driver, affecting texture rendering (I presume it's more related to mipmap) in ut2004. Going to attach some screenshots.

I already bisected the issue and the commit introducing the regression is:
intel: Add an AllocTextureImageBuffer() implementation using miptrees.
http://cgit.freedesktop.org/mesa/mesa/commit/?id=e928c34d3ec54bb8a6b80036e6b6a91977bf0865

Added Eric to CC.

Greets,
Tobias

P.S.: System specs:
Intel Corporation Arrandale Integrated Graphics Controller
vanilla-kernel 3.0.6

Issue is still present with latest mesa git master (79653c12d6da4d89aaa73e4e8260a84d91f93593).
Comment 2 Tobias Jakobi 2011-12-15 19:23:57 UTC 
Issue seems to be fixed with recent mesa git master.
