Does this look like a hacked computer?

Can someone help me to figure out what this is. I am using macbook pro and the other day i saw a blinking box for 2 minutes and got a screenshot. it looks like a distorted picture. is it related to a known virus?

Also gamed process is trying to connect to internet every other minute. Is this something normal?

I am using OS El Capitan 10.11.4 and little snitch

Thanks

Run ClamXav and Malwarebytes for Mac, it just looks like a distortion though

That is part of Game Center and is normal.

Viruses! Why does it always have to be viruses? Why not ghosts or aliens in the machine?

This looks like a poorly-rendered popup to me. Maybe some code got mangled on its way from server to browser.
