Stroke automatically tapers to minimum

Hey, so I don't know if others have seen this same thing or not, but I've noticed on Fresco when you release off the screen, the line will automatically taper down to zero or whatever your minimum brush size is. I notice it most on the standard hard round variable brush and making quick strokes, but a really good way to replicate it is to turn smoothing all the way up and draw a wavy line. It's only at the END of a stroke, never the beginning, which I guess makes sense given how the computer interprets the touch on the screen.

It looks really bad, because a lot of my lines have these weird triangular tails that don't follow the curve or angle of the stroke. Like, they just sort of veer off into a weird direction and taper into a really severe point. Is there a way to get rid of this, or is it just how Fresco works on the iPad?

I really love Fresco, and I've recommended it to a lot of other artists as an alternative to being tied to their Cintiqs. In fact, a handful of people have actually bought iPads because of the work I've shown them that I've made using Fresco. However, after realizing what's going on with this taper issue, I will probably stop using Fresco and go elsewhere if I can't get this figured out.
