I can confirm that the problem exists.

>From the debug log:
--------
017c:fixme:d3d_shader:shader_glsl_interpolation_qualifiers Unhandled
interpolation mode 0x3.
017c:err:d3d:wined3d_debug_callback 000000000C10E140: "GL_INVALID_ENUM in
glTexBufferRange(internalFormat GL_RGBA8_SNORM)".
017c:err:d3d:wined3d_debug_callback 000000000C10E140: "GL_INVALID_ENUM in
glTexBufferRange(internalFormat GL_RGBA8_SNORM)".
017c:fixme:d3d_shader:shader_glsl_interpolation_qualifiers Unhandled
interpolation mode 0x3.
--------

The problem seems to be that the application is passing GL_RGBA8_SNORM to
glTexBufferRange as an internal format, but glTexBufferRange doesn't support
GL_RGBA8_SNORM as an internal format.

I replaced GL_RGBA8_SNORM with GL_RGBA8 to test it and that seems that fixes
it. Would it be correct to add checks for SNORM textures in glTexBufferRange?
