Hi,
Thanks for the review. It's strange for Owl to effect rendering by any means since it's supposed to be light and quick. Would it be possible for you to send me a more detailed description of the issue? I'd like to know if there are particular sites where you observe a slow down, your platform (Operation system) and Owl version. This information would help me fix this. You can get in touch via http://sidhant.io/get-in-touch or mail me at dev@sidhant.io. Thanks
