             Bug #: 43477
           Summary: rendering errors in unigine tropics and sanctuary
                    (regression)
    Classification: Unclassified
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: aaalmosss@gmail.com


Some shaders fail to compile with mesa 7.12-dev, this is printed to console a
couple of times:
GLShader::loadFragment(): error in
"core/shaders/meshes/fragment_base_light_omni.shader" file
defines:
UNKNOWN,QUALITY_LOW,QUALITY_MEDIUM,QUALITY_HIGH,MULTISAMPLE_0,USE_INSTANCING,USE_TEXTURE_ARRAY,USE_DEFERRED,USE_TRANSLUCENT,USE_PARALLAX,USE_REFLECTION,OPENGL,USE_PSEUDO_INSTANCING,USE_PSEUDO_TRANSFORM,BASE_LIGHT_OMNI,OMNI,SHADOW,PHONG_RIM
0:460(18): error: syntax error, unexpected NEW_IDENTIFIER

In tropics the night scenes are rendered incorrectly, in sanctuary almost
everything is gray. With 7.11 these demos render correctly. Tested on hd6850.

Probably this is a known bug with GL_EXT_TEXTURE_ARRAY in Unigine engines and
glsl < 1.30. IIRR they are using the extension without enabling it in the
shaders.

Disabling the extension completely with the environment variable should help:

MESA_EXTENSION_OVERRIDE=-GL_EXT_texture_array

Yes, disabling that extension fixes the problem. Is it so rare that an opengl
implementation supports GL_EXT_TEXTURE_ARRAY but not glsl 1.30? The extension
spec is written against glsl 1.10.

BTW, how far is r600g from supporting glsl 1.30? AFAIK the intel driver already
advertises glsl 1.30 support.

same result with Intel GMA 4500 with Mesa 8-series and Mesa 8.1-devel from git

This still happens on nouveau, despite OpenGL 3.0 advertised.
