I figured that as most related functions were stubs.

I do think it's odd as well since a more basic function can handle it.

After it loads it shows:
fixme:opengl:wglSwapLayerBuffers (0000087c, 00000001)
..repeated until exiting the game.
So it's basically switching the main layer over and over again?
I don't think it uses other layers. Because I think there would be a graphics corruption if it did. None have been observed so far.
Heh, since I'm a beta tester, I can ask blizz why they even use this function, and see if they respond.

And it's the best running game I've seen running under wine. =)
