Then I'd expect the same behavior to happen if you do "M-5 M-v" instead of turning the wheel. Does it? If M-v doesn't reproduce the problem, then what about removing the tricky code, and leaving just (funcall mwheel-scroll-down-function amt) without all the rest? I cannot understand why we need the rest, maybe I'm missing something. mwheel-scroll-down-function is by default scroll-down, exactly the same function called by M-v, so the results should be the same, assuming that 'amt' is 5 when turning the wheel. > The behavior is different depending on how fast the mouse wheel is > turned.

Just to make sure we are not barking up the wrong tree: this is in "emacs -Q" with no customizations of any scroll-related variables, like scroll-margin, scroll-conservatively, etc., right?
