BUG: gtk_widget_hide_all for frames

[Ullrich Hafner <hafner informatik uni-wuerzburg de>]

Hi,

I think I found a bug in the current devel-release of GTK+ (1.1.5, and
snapshot 98/12/03): If a widget (surrounded by a frame) is put within
a scrolled window and I call the function gtk_widget_hide_all for this 
frame, then the widget is hidden but not the frame (actually it is
hidden but the image is still on screen, I must switch workspaces to
refresh the screen).
Attached is the code to reproduce the bug. I also made two GIF images
that visualize this behavior:

P.S: compiled with 
gcc -Wall -g -O3 demo.c -o demo `gtk-config --cflags` `gtk-config --libs`
on a libc based Intel-Linux system (XFree 3.3.2).

   gtk_container_add (GTK_CONTAINER (main_window), dialog);
   gtk_widget_show_all (dialog);

   gtk_widget_show_all (main_window);

   gtk_main ();

   return 0;
