menu of gedit on Ubuntu 16.04

Where is the menu of gedit? It doesn't show up.

Also, as you can see on this image the buttons are gone:

There are only two buttons here (you can see the "open" button on the image and the "save" button is on the right, which I haven't captured on the image)

How can I search for strings now?

Edit 1: As I have discovered, this is also the case for the terminal and nautilus. No menu shows up when I hover over the top. BUT, when tuing into a guest session I can correctly see the menus. What is wrong with my old, migrated user?
