Flickering/Blinking

Hi, I was wondering what may be causing flickering/blinking on the sidebar when you scroll down and hover over the recommended posts or the left sidebar. I already set the refresh interval to 0. It was also working perfectly fine the first time I tried it. I would really appreciate if you could give it a look and let me know what’s going on, I really like the plugin! http://megawhat.com/hello-world/2014/05/02/

Thank you!
