The background for this video has become superimposed on my entire computer screen. How do I fix it?

I played this on fullscreen a few minutes ago,, and it turned out to be one of those videos where the picture goes diagonal and splits in two when you play it on fullscreen. Nad now this picture is superimposed on my entire computer screen, even after I turned the computer off. How do I fix this? The video is this:https://www.youtube.com/watch?v=M4x-GJNmgVs

Update:

Ps I have a Mac OS

    Not possible to be seen if you turn the computer off. Quit spamming "advertising" for a Youtube link....
