I can replicate on ms windows using just:
(setq scroll-margin 5)
(setq scroll-preserve-screen-position 1)
(setq mouse-wheel-scroll-amount '(1))
Open a large file. Make sure you're at the start of the file
M-<
Scroll down with the mouse wheel and within a few clicks point jumps to the
middle of the screen. A few more and it jumps to the end of the file.

The cursor jumps from within the scroll-margins to end of file and back and
forth.
Some of those settings can probably be removed but scroll-margin is
probably important.
