I noticed the background color worked when I put it in the application. However I still don't understand why.
I looked around container...@2844 . Do you mean the comment header above updateDisplayList I really want to understand this.

Set no background or backgroundAlpha=0 on your drawing Canvas. Layer your containers if you want a background color, or set it on Application in his case. It maybe possible to add a Sprite on top of the Canvas and draw into that too, maybe.
