In metacity/src/core/constraints.c,

 /* Workaround braindead legacy apps that don't know how to
   * fullscreen themselves properly.
   */
  if (meta_rectangle_equal (new, &xinerama_info->rect) &&
      window->has_fullscreen_func &&
      !window->fullscreen)
    {
      /*
      meta_topic (META_DEBUG_GEOMETRY,
      */
      meta_warning (
                  "Treating resize request of legacy application %s as a "
                  "fullscreen request\n",
                  window->desc);
      meta_window_make_fullscreen_internal (window);
    }



I'm not familiar with metacity code, but I think my maximizing and
decoration disabling request is making the size of the activity window
as equal to the size of the screen, which Metacity is interpreting as
a fullscreen request.
I'll do a custom build of Metacity with this disabled and see how it works out.
Cheers,
