The following link works quite well when running in the silk browser on a kindle fire HD. The responsiveness is quite good. It uses touch move events to trigger canvas lineTo()s.

But, when using this html file in a cordova android app (with or without including the cordova js file) on the same kindle fire HD, the responsiveness is really poor.

The line being drawn follows your finger (at quite a big distance) as you move it rather than being drawn directly underneath it.

This suggests to me that there is some lag in event processing when doing this with a cordova app that isn't present when using the silk browser.

Can anyone shed any light on why this is, and if there is anything we can do about it please?

You can grab the entire source from the url above. Everything needed for this test app is in that html file.
