So if you thought your new shiny Yoga had a bad touchpad, it may not be the touchpad at all! My Yoga 720 15.6 was acting really strange where every so often using the touchpad wouldnt work, and trying to use the keyboard wouldnt work at all. I first thought it was a touchpad issue but realized that this is a system wide issue. Something is causing Windows to start hitching.
I turned off Adaptive Brightness in Power settings and the problem has gone away!
I had a hunch it was this when I noticed the adaptive brightness was doing its job of gradually changing the brightness but looked like it was lagging while it was dimming/brightening itself.
Lenovo Support: Please address this problem through any channels necessary because I want Adaptive Brightness but right now I have to have it disabled in order to use Windows without any hitches.
