Jagged Lines in Storyboard Pro

Hello! I downloaded Storyboard Pro a few days ago, but I haven’t been able to use it properly yet because the pen pressure (?) keeps glitching out. When I draw a line, parts of it become very jagged/angular. Even stranger is that this only seems to happen on one side of my screen. I can draw a line across my screen and it will just start freaking out out and becoming jagged once I cross some invisible barrier, it seems. I’ve taken a screenshot of the problem and attached it to this post so that you can see what I mean.

In Harmony, my pen pressure works fine with the same tablet, so this is only happening in Storyboard Pro. I’ve tried uninstalling/reinstalling the program to no effect. I haven’t tried uninstalling/reinstalling the drivers on my tablet yet because I wonder if that’s really the problem when pen pressure works fine in Harmony.

Also, in case this is relevant, I use a monoprice tablet, and I have Windows 10 on my laptop.

Any help is appreciated, thank you for reading this!
