Canvas texture update cause performance issue in Firefox and Safari

This seems to be a browser limitation. I get the same result by setting the canvas resolution to 2048x2048 in the fiddle from this post: Three.js + Fabric.js. The performance of Firefox and Safari is bad, Chrome runs smooth at 60 FPS.

I suggest you file a bug at the browser’s issue tracker (e.g. https://bugzilla.mozilla.org/home) since this seems to be no three.js issue.
