I emailed nvidia a summary of the issues with a link to this bug. Nvidia is
free to change the internals of their drivers and this is most likely what they
did in order to fix issues like the compiz black window bug and other issues.

Most of the time you enable multisampling from nvidia-settings as most apps
don't offer such settings. Some games do offer them but those use it in a
different way than Wine. First of all 'classic' GLX programs select a pixel
format and create a toplevel X window using this format. In case of Wine we
aren't rendering GLX to a toplevel window but to a subwindow of this toplevel
window. The reason for this is that in case of GLX you need to specify the
pixel format at window creation time whereas on Windows you do it afterwards.
This behavior is something the Nvidia drivers might not like. Second Direct3D
allows you to 'reset' the pixel format of a Window which again OpenGL doesn't
offer, so we kill the subwindow and then create a new one. Perhaps again this
is something the drivers don't like in all cases.
