As someone who debugs graphics drivers for a living, I assure you it's the same from the other side. Except the gigantic closed source binary blob is some AAA game, benchmark, or a popular game engine demo. Also often the developers are using the API against the specification, but one of the GPU vendors is more lenient than the other so it works for them and they are already shipping the game, too late to fix.
