That may be that :

gtklayout.c :

  /* We don't have any way of telling themes about this properly,
   * so we just assume a background pixmap
   */
  if (!GTK_WIDGET_APP_PAINTABLE (widget))
    gdk_window_clear_area (layout->bin_window,
                           area->x, area->y, area->width, area->height);
