In emacs-25 either use something like

#if !GTK_CHECK_VERSION (3, 20, 0))
          xg_frame_resized (f, -1, -1);
#endif

or, as Matthias proposed, in xg_frame_resized write

  if (pixelwidth == -1 && pixelheight == -1)
    {
      if (FRAME_GTK_WIDGET (f) && gtk_widget_get_mapped (FRAME_GTK_WIDGET (f)))
	{
	  gdk_window_get_geometry (gtk_widget_get_window (FRAME_GTK_WIDGET (f)),
				   0, 0, &pixelwidth, &pixelheight);
	  if (pixelwidth <= 1 || pixelheight <= 1)
	    return;
	}
      else
	return;
    }
