Starting with emacs -Q, change the path to an image that is taller than a line of text.

;; Evaluate this
(face-remap-add-relative 'default
'(:stipple "/path/to/large/image.jpg"))

;; Evaluate this once
(scroll-down -3)

;; Evaluate this 3 times
(scroll-down 1)

;; Notice that the top 3 lines now are repeated using the top portion
;; of the image.

;; Now evaluate these
(scroll-down -3)

(scroll-down 3)

;; Notice that the top 3 lines are now correct.

Also, sometimes moving point (especially with
`backward-paragraph' and `forward-paragraph') will cause lines to
change which portion of the image they display.  This is a little
less predictable, but evaluating (scroll-down -3) and then
repeatedly using `backward-paragraph' will cause lines to change.
Then once the window scrolls to the top `forward-paragraph' will
cause them to change again.  

It seems it may be related to when the cursor is at then end of a line.

Thanks,
Ivan Andrus
