Yeah, my understanding and explanation as recorded in this bug is scattershot,
misleading, and wrong.

I've meant to update it with an accurate summary of the problem, but there
seemed to be hostility towards the idea of matching nvidia's behavior instead
of demanding everybody else change their (technically buggy but in practice
perfectly correct) software so I haven't bothered.
