For what it's worth, I was suffering from exactly the same thing and
eventually unbound the mwheel stuff altogether and simply rebound them to
the following. After that, scrolling was sane again.
(defun scroll-up-one ()
(interactive)
(scroll-up 1))
(defun scroll-down-one ()
(interactive)
(scroll-down 1))
(defun scroll-up-double-speed ()
(interactive)
(scroll-up 3))
(defun scroll-down-double-speed ()
(interactive)
(scroll-down 3))
(global-set-key (kbd "<mouse-4>") 'scroll-down-one)
(global-set-key (kbd "<mouse-5>") 'scroll-up-one)
(global-set-key (kbd "<double-mouse-4>") 'scroll-down-double-speed)
(global-set-key (kbd "<double-mouse-5>") 'scroll-up-double-speed)
(global-set-key (kbd "<wheel-up>") 'scroll-down-one)
(global-set-key (kbd "<wheel-down>") 'scroll-up-one)
(global-set-key (kbd "<double-wheel-up>") 'scroll-down-double-speed)
(global-set-key (kbd "<double-wheel-down>") 'scroll-up-double-speed)
