I recently moved from 14.04 LTS to 16.04 LTS with all the resulting software upgrades. There have been a number of UI changes, but this one is most annoying.
Windows that are not maximized do not show the window name/title anywhere. The menu bar does not evens display the application name; it's just "Text Editor" for gedit or "Files" for nautilus. The title bar just sits empty.
This is very inconvenient for many reasons; for instance, if you have multiple (untabbed) instances of gedit open it's hard to tell which file is open where. Titles are shown for the currently selected window in the application switcher, but that's little consolation.
How can I get window titles back to title bars?
I run Ubuntu 16.04 LTS with Unity 7.4.0.
