Reproduced rendering failures (not exactly the same, but possibly related) here. commit 5bb05c6e6d596d66c177e42a36128d2ca2e300aa Author: Eric Anholt <eric@anholt.net> Date: Wed Feb 13 21:21:45 2013 -0800 i965/gen7: Set up all samplers even if samplers are sparsely used. In GLSL, sampler indices are allocated contiguously from 0. But in the case of ARB_fragment_program (and possibly fixed function), an app that uses texture 0 and 2 will use sampler indices 0 and 2, so we were only allocating space for samplers 0 and 1 and setting up sampler 0. We would read garbage for sampler 2, resulting in flickering textures and an angry simulator. Fixes bad rendering in 0 A.D. and ETQW. This was fixed for pre-gen7 by 28f4be9eb91b12a2c6b1db6660cca71a98c486ec Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=25201 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=58680 Reviewed-by: Kenneth Graunke <kenneth@whitecape.org> NOTE: This is a candidate for stable branches. Cherry-picked to the 9.0 branch: be7048477a2989bd11ab590c65ea1515f764a86c It will be available in Mesa 9.0.3. |
