Textures are rendered incorrectly in unigine heaven on latest git drivers with kernel 3.5.0 when shaders are set to high and ambient occlusion is on. The problem is fixed when exporting MESA_EXTENSION_OVERRIDE="-GL_ARB_shader_bit_encoding"

Hardware is juniper.

I can reproduce this on my system:

Unigine Heaven 3.0
Kernel 3.5
Gallium 0.4 on AMD RV770 -- 2.1 Mesa 8.1-devel (git-be42a45)
ColorTiling2D enabled
Comment 2 Benjamin Bellec 2015-08-15 12:41:49 UTC 
Can you retry with an up to date Mesa ?
I guess it's now fixed.
Comment 3 Andreas Boll 2015-08-16 08:41:26 UTC 
It works for me. Tested with unigine heaven 4.0 and enabled GL_ARB_shader_bit_encoding.

Gallium 0.4 on AMD BARTS
3.3 (Core Profile) Mesa 10.6.4
