When I write a comment to students on their papers, my handwriting is smoothed by Acrobat, and often distorted beyond recognition, sometimes taking my letters and spiking them above and below the word. I've turned off the "smooth line art" in preferences. I am using a Wacom CTL 490 tablet. I'm sure it's not the tablet because it works perfectly in Onenote and Photoshop. Even if I could tone the smoothing down a little so it my handwriting is still readable, that would be fine.
Any help would be greatly appreciated.
I have the same issue.
I tried going to Preferences > Page Display > uncheck "Smooth Line Art" and restarted the application. It still smooths my handwriting.
I am running on a mac version 10.13.1 and there are no new updates for Adobe Acrobat Pro. I have a similar Wacom tablet that draws fine with other applications like Photoshop.
