Here (24.3.50) the same problem exists. I did know it for a long time
and always thought that's just the way emacs displays images. Now that I
learned that this is not the intended behaviour I searched a little and
found out that disabling fringes is the cause:

(fringe-mode 0 nil (fringe))

Without this setting I can scroll both ways flawlessly.
