--- Comment #11 from Paul Gofman gofmanp@gmail.com --- I actually missed the point with framebuffer object, your card actually claimed to support that initially, setting MaxVersionGL to 1.0 should have disabled it. You can probably try running with MESA_EXTENSION_OVERRIDE=-GL_ARB_shading_language_100 but without setting any tweaks in registry (removing MaxVersionGL override).
