   emacs -q --no-site-file
   C-h C-n
   M-x ruler-mode

   <down>...                                   ; all works as expected

   M-x set-variable scroll-conservatively 1000 ; any non-zero value

   <down>...                                   ; bug happens when cursor
                                               ; is in the last line and
                                               ; you scroll down

Thank you.  Yes, this recreates the redisplay bug.  

However on my (fairly fast, 850 MHz i686) machine, the repeated lines
show only momentarily, not for several seconds.  After the extra
characters appearance, the extra characters vanish and lines look as
they are supposed to.

Using yesterday's CVS snapshot, Thu, 2002 Jul 18  23:22 UTC,
GNU Emacs (i686-pc-linux-gnu, X toolkit),
with the patch from address@hidden (Kim F. Storm) to xdisp.c 
(that fixes the other problem),
Emacs started with:

    emacs -q --no-site-file --eval '(blink-cursor-mode 0)'
