Thanks! I've tracked this down and it should be fixed in mesa commit d37f90f131ff18f0902e79853b2dbdfd494baa17. |

I have this software setup: kernel: commit 965a47fb8ec0a72324aad8b9c0bd1c8b98cc7ca1 (3.4.0-rc2 nouveau, master branch up to "drm/nouveau/bios: fix regression on some nv4x board") mesa: commit b2df031a959f36743527b9abc89913ce4f895de3 ("r300/compiler: Fix nested flow control in r500 vertex shaders") libdrm: master branch commit 292da616fe1f936ca78a3fa8e1b1b19883e343b6 ("nouveau: pull in major libdrm rewrite") ddx: master up to commit fb3a36b1e5af0f81bb266da894d3442eed8e4e55 ("nve0: initial exa/xv acceleration for kepler chipsets") X server - 1.10.4 Hardware: 01:00.0 VGA compatible controller: NVIDIA Corporation NV43 [GeForce 6600 GT] (rev a2) - AGP version. With this cobination at least demo program "lodbias" from mesa demos seems broken. It displays mostly random garbage, you can only very briefly see original image when LOD factor become negative.
