Author page glitch help?

Hey all

I have the plugin installed and updated to the latest version
I updated my profile and went to see how it looked on the page but nothing loaded (Using chrome)
So I changed over to firefox and same issue.
I then opened up the debug console to try figure it out and it loaded.
I then found that the page is loading, just not rendering until the resolution changes on the page

Is this a known issue? and something I can easily fix?
