Everything works fine except for the first seconds. Here's a quick .GIF to show the issue:\r\n\r\n![44ab54ebd82ef3c8b9d33f0cef113fbc](https://cloud.githubusercontent.com/assets/2464663/13010243/1d430e64-d1a1-11e5-8f0c-cff16c352030.gif)\r\n\r\nPretty strange, I have to admit.. After some time (like a few seconds without dragging) or at the end of the first drag, the `mix-blend-mode` takes effect and the white is being removed. Then we don't have this `clearRect` 'looking-like' issue.\r\n\r\nAny ideas? Thank you a lot!"}}
