Hello,

What are the differences between adding a canvas gadget or a screen? Is one the html5 canvas and the other handled by pixiJS?

Both are html5 canvas, the difference is WebGL : the screen is GPU accelerated (but it need to be refreshed every frame) while the canvas isn't.

You should select which one to use based on movement : do you need a lot of update to your canvas? Go screen. Will your canvas be mostly static? Go Canvas.
