    Flush any outstanding stuff in the window in non-buffered get_internal_paint_info case
    
    We return the raw window drawable, so its likely the app will do some
    weird stuff to it, like draw using non-gdk operations. We don't want
    the app to see any half-drawn state, so flush everything.
    
    This fixes a scroll issue in firefox at least.
