RE: Dell XPS 13 9350 touchpad two finger scrolling "jumps"
yes I also had this behaviour with Windows 10 in the chrome browser,
after reverting the direction it got better and after deactivating two finger pinch to zoom it went away completely.
In the Edge browser there was no problem.
This is indeed a very annoying issue but i think it is software related because I don't have any issues since I am running Ubuntu on my XPS 13
