Both vertically and horizontally work fine here. When I place three fingers diagonally thats when things start to get funky.
 
I've went to test this again in several stores and again all 2016 MBPs have this problem. I tested several 15" and 13" ones with and without touchbar.

I will not replace my device and hope there will be a firmware upgrade some time.
 
I'm going to bring this back up to the top as well. Mine is definitely sporadic at best and was wondering if anyone knows of a fix yet for this?
Thanks!
