The same regressions affects most 3D games on Mac OS X Leopard. The result is a
completely blank window!

I'm using virtual desktop mode for all games that want to go full screen on
MacOS, because until recently, XQuartz could not change resolution.

Commenting out set_mwm_hints in sync_window_position restores normal behaviour.
The attached patch was generated with:
    TRACE("mwm_hints %x+%x\n", style, ex_style);
    //set_mwm_hints( display, data, style, ex_style );
