I found some problems with your code. You can check here the solutions I found.

The fixes I needed to do where:

1. To create a Graphic you should use createGraphics (you were using createCanvas instead).
2. As you are translating the shape you draw on the canvas, you should also translate the trails themselves in the trails layer graphic.
3. As you draw the trails, you should also use push() and pop() to save the settings of the graphic at each frame, so the translation doesn't accumulate from one frame to the others.
