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.
