Thanks Fredrik! Based on that, I'm closing this as RESOLVED/NOTOURBUG.

@Rune: Feel free to double check by running glxinfo, but I believe the ordering
is correct: multisample configs are always sorted later, as required.
Using glXChooseFBConfig() does seem like a good idea...could guard against
future problems (though I don't know what), and should simplify the code a fair
bit. Also, KWin's EGL backend uses eglChooseConfig() and it never had this
problem. That would also make the GLX and EGL backends more similar.
Thanks again.
