Davina,
My guess is that the extra decorations don't go away because the
gtk_widget_draw doesn't erase any of the backgrounds your decorations
are drawn on -- they normally come erased for you in the exposure
callback. You could easily verify this by de-focusing your widget and
causing it to redraw by invalidating it by another window. The part that
you invalidate should redraw without the decorations.
