emacs24 as shipped by debian breaks "scroll-margin".
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=681991
It seems that setting scroll-margin on *any* value breaks the redisplay
while scrolling.
Try with the following (under a graphical session):
emacs -q
open the tutorial, scroll with the arrow keys until you reach the bottom.
Everything looks ok.
kill emacs. Start again, this time:
C-x set-variable scroll-margin 5
open the tutorial, scroll down with the arrow keys until you reach the
bottom. Text on the page looks *badly* garbled (this is not just
character left-overs from the previous screenfull, a lot of lines look
repeated at some point in the same line).
