Comment 7 for bug 511656

bug confirmed from another user too.
It seems that we'll have to choose between compiz or rgba. The following lines from the rgba patches prohibit the shadow from compiz:

src/nautilus-window.c (line 156)
if (colormap && gdk_screen_is_composited(screen))
{
      gtk_widget_set_default_colormap(colormap);
}

I'll make an gconf parameter to switch between rgba or normal colormap, so compiz could draw his shadow depending on the user choice. But i am little busy actually so i don't know when i implement this.

Thx to jumpinjack who solved this.
