With the current CVS snapshot I can't reproduce the problem,
however I was able to do that before (a week ago)
Just drag the scroll bar and carefully move it up & down
so it will scroll a couple lines only.

Examine the top line of the buffer.
Todays CVS works fine strangly.

This happens for me in all Emacs versions, (Lucid Xaw scrollbars,
Lucid native scroll bars, GTK and Lesstif/Motif).  It must be a

To see it clearly I do:

% emacs -q --no-site-file
C-h t

Then carfully scroll down one line, the top line is shifted to the
left.  A C-l fixes it.

Scrolling typically jumps several lines, and clicking on the scroll
down arrow scrolls one line ok.
