Not sure I understand; are you saying that we need to keep track of framebuffer comlpeteness on our end (because we might have a more restricted model of completeness than the underlying implementation) and then check that before issuing drawing commands?

I filed this bug at a time when I believed that we systematically had to check everything on our end. So I'm not implying anything subtle here. If you think that we can rely on the GL here, feel free to mark as INVALID :-)

Yeah, I don't think there is -- especially since framebuffer completeness is somewhat up to the whim of the driver, I don't think GL defines any required combinations :(
