This question already has an answer here:

After following some beginners tips/tricks for Ubuntu 12.10, I noticed that Chrome/Chromium windows shows the minimize, maximize and close button twice. I tried undoing what I did, but that didn't fix the issue.

Why is it so?

This question was marked as an exact duplicate of an existing question.

If chromium is not maximized, it will show two sets of {minimize,maximize,close} buttons due to the way it's coded.

I see, that's helpful to know. Thank you. – Diego Feb 9 '13 at 23:26
This is not really a complete answer. Everything a program does is "due to the way it's coded." I recommend expanding this to explain how the buttons are built into the side of the tab bar, and also appear due to Unity. (It would be best to provide more details than that, but any amount of detail, including less than this, would probably be helpful.) – Eliah Kagan Feb 17 '13 at 15:44
