Windows 10: How do I remove this white bar that appears at the top of the screen when I go full screen...

So I recently built a pc and whenever I try to play a video game such as Minecraft this white bar appears at the top of my screen with the option to close, minimize or see all my tabs in the top right-hand corner and the game I am playings name in the top left. Is there any way I can fix this?

Chrome---lots of white space at top of screen

Not exactly sure how to word this. When I go to Chrome, this is what I see, from top to bottom:

1. Tabs at very top.
2. Address bar.
3. Below address bar, huge amount of white space, then a line.
4. Content.

The huge white space takes up precious screen space. I want to get rid of it. At one point, Chrome/Google had some stuff there, which I deleted. But I cannot find a way to remove the white space. This wasn't there when I was running Windows 7 two weeks ago.
Now I am running Windows 10.

Thanks.
