When safari or Chrome loads localhost, it shows a small load time indicator

I noticed recently that when using Chrome or Safari for developing, I see this little indicator in the upper-left of the screen that shows me the load time of the page. If I click on it will change positions I think, and disclose a larger panel showing more info about the page load.

I feel a little silly but I don't know what this is -- it isn't an extension AFAIK (I disabled all extension), it happens in BOTH Safari and Chrome, and it only happens when developing on 127.0.0.1 or localhost

SO.. my question is, can I 1) disable it, or 2) move it to another corner on the window?

It's a patently straightforward usecase: All I want to do is take a screenshot of the "Hello World" that is below the indicator, but it is covered up.

I don't remember seeing this until recently I am assuming it is something I just never noticed or something new in Webkit
