render fails in some cases where initial path crosses itself

[toblerpwn]

while drawing the initial path on an empty canvas, if your original line creates a circle, and the path crosses its origin, it can in some cases drop rendered frames when you 'release' your finger and end your current path.

however, if the canvas is re-drawn (i.e. if you begin another line), it self-corrects immediately.

in the following video demonstration, i use black for the first path, and pink for the second path: https://youtu.be/oBBSGfU941k

when i release my finger from the first path's drawing, you will see much of the drawing disappear. the moment i begin the second (pink) path, you'll notice everything re-renders as expected immediately.

This appears to be resolved in the latest version 0.4.1. I'll monitor this for the next release or two & close if the problem remains fixed.

I can confirm this is fixed for us.
