Sorry for the thread revival but I've got a work around for this, the share screenshot gesture is gone, and so is the action bar and task bar gestures...! I've got the 12v64 but I bet its the same! Theres no info online on how to fix this and its an issue for loads of 2 in 1 tablets with win10 not just Linx!
Short story, disable the Win key on the keyboard, means you can't use it, and the Windows button stops working on the bezel too, but it stops the annoying swipe gestures!
The long story... I'll write a separate thread!
Currently to block the 'share screenshot bar' I'm using an open source program called 'sharpkeys' (no affiliation, just found it and does the job), it has a learning mode, it listens for a key press, you basically give it the windows key (or the trackpad gesture to prove it) and you reassign that key to do nothing!
It only blocks 1 key, so you can't do keyboard combos like 'win+h' (which is actually what gets called when you swipe down from the top of the trackpad, it sends a keyboard combo out...)
There is bound to be a more elegant solution, at a driver level or such, but that's where I'm at ATM, only had the tablet a couple of days!
