Hi, I also am having a scrolling issue on two Asus computers while this function/feature works in our Lenovo:
the scrolling inside the fences with two finger gesture is the feature I am speaking of. It wont work in Windows 10 in our two Asus laptops, will work in Windows 10 in the Lenovo.
In all other aspects (to the extent I've tested so far) of other apps the 2 finger scrolling gesture works in the Asus machines as it should. The Asus machines scroll fine with the scrollbar by mousing to scrollbar and grabbing and holding it while sliding it up and down manually (a true chore for a 2 finger scroll gesture addict like me) thru the high icon/shortcut volume fences.
