Created attachment 301484 [details] Epihany vs Firefox I'm using Epiphany as a test but it's the same with all web browser using WebkitGtk2. When using a touchpad (with and without smooth scrolling), scrolling is ok, same behaviour as Firefox. When using a mouse wheel, scrolling increments are too short and scrolling a whole page is killing my finger! Look at attachement, one mouse wheel on Firefox and one mouse wheel in epiphany. Don't know how Gecko deal with that but WebKitGTK should not use same adjustment for touchpad and mouse wheel.
Manage to bypass this issue here: https://github.com/gnumdk/eolie/commit/4c46ff1b135d89d69b8a1b4741d99e694d26a457 But webkitgtk should be able to manage this by default.
