Description Martina Kollarova 2016-10-10 12:47:24 UTC

Mesa currently sets ctx->Version to the highest version the driver supports for
the selected profile, which may be higher than the GL version requested in
glXCreateContextAttribsARB. An example of a user bug due to this behavior: https://bugs.freedesktop.org/show_bug.cgi?id=95374.

There should at least be some documentation about the current behavior in the gl_context struct.

As far as I know, that's how GL is expected to work.  Other implementations do this as well.  It's unlikely to change.
