Describe the bug
The scroll speed is absurdly fast when Scroll Wheel Resolution is enabled. I found solutions for mice that use evdev as the driver, but M720 uses libinput so I can't just use xinput to reset Evdev Scrolling Distance.
To Reproduce
Steps to reproduce the behavior:
With a mouse that uses libinput (M720, for example), activate Scroll Wheel Resolution.
