--- Comment #7 from José Fonseca <jfons...@vmware.com> ---
I suspect the problem are these lines in setup_glsl_generate_mipmap():
_mesa_BindAttribLocation(mipmap->ShaderProg, 0, "position");
_mesa_BindAttribLocation(mipmap->ShaderProg, 1, "texcoords");
_mesa_EnableVertexAttribArray(0);
_mesa_EnableVertexAttribArray(1);
Which can be executed without this line being called:
_mesa_BindVertexArray(mipmap->ArrayObj);
This patch might fix this.
