Is this a "known" (maybe gtk+ people did not see fit to mention it 
through any sensible channels to emacs people?) scrollbar issue:

Gtk+, like Qt [1], has moved away from most use of X11 subwindows.

see:
http://live.gnome.org/GTK%2B/ClientSideWindows

* Problems that will require application changes

     * emacs 23 (with gtk):
           o Sometimes when pressing Ctrl-L the scrollbars are overdrawn 
with white and not repainted. This is due to emacs using raw X 
primitives to draw on the window, while the scrollbars are client side 
emulated windows. Emacs could make the scrollbars native and this would 
make sure they weren't overdrawn
