Apple Pencil (Stylus) input problems with scrolling Unity 5.3.X

Running into a weird problem with touch input from a stylus using Scrolling UI inside Unity.

I've traced the problem down to Stylus input, and Scroll windows.

When using the Apple Pencil, and Unity's new Event system, regular buttons seem to work fine for navigating/getting the "touch" events to select buttons, however, if i throw a scrollrect into he equation and make a scrollable window with items inside, the drag works perfect, but when trying to select a button, it can sometimes takes 3-5 clicks to get a selection to pass through.

I'm not sure if its iOS, as iOS double samples the Stylus input at 240Hz, effectively doubling the number of inputs tracked, and its seeing slight "movement" from the tip, or if its because theres a bug in the Unity code with the newly supported Apple Pencil.

I could really use some help though, as its maddening trying to get what should just work, working. Btw, finger input works as expected, so its definitely narrowed down to the Stylus itself.

 

Please submit a bugreport.
Thanks!

 

I wasn't sure if it was a bug, or something i was doing incorrectly...

I will submit a bug report now though, thanks!
