The title pretty much sums it up, I'd like to avoid that the scroll continues when I release the touchpad. Here's my custom variable about the mouse wheel behaviour:
'(mouse-wheel-scroll-amount '(1 ((shift) . 5))) '(mouse-wheel-progressive-speed nil)
To be honest, I'm not sure whether this is is actually inertia or the scroll operations stack up and get executed with some delay hence causing the effect.
The behaviour is observed with
emacs -q as well.
