The black boxes are gone but there are other rendering issues. I've create an apitrace [1]. There is a shader that fails to compile due to a shader bug but thats not the problem as the trace runs fine on the Nvidia blob. Running on Nvidia also produces warnings: "Texture state usage warning: Texture 0 is base level inconsistent. Check texture size."
