So I reinstalled my job-pc, Latitude E7250 from W10 v1511 to W10 1607. (Win10 x64 Enterprise)
Everything works fine except 2-finger-scroll, witch worked in 1511.
It often needs 2-3 tries before it works, and if I lift the fingers and try to scroll again it takes several more tries before it works.
There is only one driver for the touchpad, it is the same I had before the reinstall.
What to do about this?
