--- Comment #4 from Marek Olšák <maraeo at gmail.com> ---
The apitrace contains invalid OpenGL calls, which may work with incorrect
drivers, but not with Mesa. This is the list of GL errors:

Mesa: User error: GL_INVALID_ENUM in glTexImage2D(incompatible format =
GL_DEPTH_COMPONENT, type = GL_DEPTH_COMPONENT)
Mesa: User error: GL_INVALID_ENUM in glTexImage2D(incompatible format =
GL_DEPTH_STENCIL, type = GL_DEPTH_STENCIL)
Mesa: User error: GL_INVALID_OPERATION in glTexImage2D(incompatible format =
GL_BGR, type = GL_UNSIGNED_SHORT_5_6_5)
Mesa: User error: GL_INVALID_OPERATION in glTexImage2D(integer/non-integer
format mismatch)
Mesa: User error: GL_INVALID_VALUE in glBindAttribLocation(index)
Mesa: User error: GL_INVALID_FRAMEBUFFER_OPERATION in glClear(incomplete
framebuffer)
Mesa: User error: GL_INVALID_FRAMEBUFFER_OPERATION in
glMultiDrawElementsIndirect(incomplete framebuffer)

The GLSL compiler also detected uninitialized variables in various shaders:

0:249(28): warning: `nNormal' used uninitialized
0:252(14): warning: `material' used uninitialized
0:252(14): warning: `ROUGHNESS' used uninitialized
0:288(54): warning: `diffuseCol' used uninitialized
0:290(37): warning: `specularCol' used uninitialized
etc.
