I got this error too on nvidia when requesting a context with a version <=
3.2, but from what I understand from the spec, this is not the correct
behavior.
The 0x2096 part corresponds to ERROR_INVALID_PROFILE_ARB (I don't know what
is the meaning of the 0xc0070000 part and if it is nvidia specific or not).
I would be very interested to know what is the behavior of others vendors
but I only have nvidia hardware here.
