I tried a number of things as well without any success. I was playing around
with the pixelformat and realised that if I remove the PFD_DOUBLEBUFFER flag
it looks much better. This lead me to suspect that the problem was related to
the buffer swapping. I turned the flag back on and put a call to glFinish
before SwapBuffers which worked great for all antialiasing modes except
Quincux on my NVidia GeForce4 Ti4200. I used screencaps to verify that the
antialiasing was indeed active.

I am not sure if this is a sufficient fix but it may point you in the right
direction. It seems that just disabling the MULTISAMPLE_ARB is not enough for
disabling antialiasing but maybe we can make it work with it enabled.
