If you don't have pbuffer support, offscreen rendering is not going to work one way or the other. So, I'm not sure it matters whether the surface is flipped or not - I guess it depends on which breaks more apps. I see no reason to flip anything in that case, but I didn't mean to change existing behavior.
If you think the skybox isn't using offscreen rendering, and is still getting reversed incorrectly, then that would be a bug.
I'd recommend trying what happens on a card with pbuffer support.
