If you believe the NVIDIA driver is wrong, please let us know what needs to be fixed and we'll look into it.
If on the other hand you can't prove that the NVIDIA driver is wrong, then please don't write a test that "fails" when you have no evidence that it isn't the test that is incorrect. Otherwise this tends to claim "this is required OpenGL driver behavior" and confuse everyone.
