Description of problem:
Quite often when scrolling down in (at least a Firefox page) results in teh page scrolling down VERY FAST the first time when I use the mouse wheel.
The second or third time I use the mouse wheel to scroll down (in the same "process") all works as usual. This is a very annoying bug, I'm not sure if it's FF or libinput.
