I append an illustration of a window configuration and a command in a
shell window that shows this effect for me.  I recompiled with the
newest sources.

It may be important (no idea) that I compiled
--without-toolkit-scroll-bars.

The effect has been visible for months, also on emacs-multitty.

In GNU Emacs 22.1.50.4 (i686-pc-linux-gnu, GTK+ Version 2.10.11)
 of 2007-08-14 on lisa
Windowing system distributor `The X.Org Foundation', version 11.0.70200000
configured using `configure  '--prefix=/usr/local/emacs-21' '--without-toolkit-scroll-bars''
