I did a little work, but actually did not find anything that could help me solve this problem. I recently switched images from canvas to vectors, which worked great for everyone except Chrome for Android (tested at 30+). In particular, in this example of using EaselJS for all my canvas materials.
UPDATE: http://jsfiddle.net/mcfarljw/hnMLU/ Check this script on your Chrome mobile phone to see the problem.
Is there anything I can do to smooth it out?

//check fiddle for live code var stage = new createjs.Stage("demo"); var stroke = new createjs.Shape(); stage.addChild(stroke); stage.update();
