Short description of error
Grease Pencil continually adds little blobs of ink to the ends of my strokes and no amount of changing settings seems to get rid of them.
I'm using Astropad for iOS/MacOS as a tablet and don't have this issue in any other software I'm using it to draw with. I've tried changing all the brush settings to get rid of the problem but nothing works.
Exact steps for others to reproduce the error
Open a new blender file
Create a Grease Pencil Object
Try drawing a Grease Pencil frame with Astropad
