pen lag on Surface Pro 2017

Hello, all, 

Has anyone experienced the cursor lagging the pen on a Surface Pro 2017?  I'm seeing this on mine, and it's bad enough that if i try to draw rapid little hatching marks, nothing at all registers on the Surface because the cursor never catches up with the pen. 

Oddly, the pen works fine in other apps, like Autodesk Sketchbook (which came with the Surface). I don't see any of these issues there, or even in the little practice pad they give you to help you set the pen pressure. Just in Photo Paint (from the 2017 graphics suite).

Help! 

Thanks in advance
