I am using 16.04.1 LTS. With the vanilla unity version that comes with the distribution.
Recently, all of a sudden (probably after some update) The title bar for application windows are no longer visible. When new application windows appear, they appear merged and attached with the global title bar.
And there is no ways to detach them, or access their menu items. (with some exceptions like firefox).
Can any one help me here? I tried using compiz manager to reset the preferences to default. It does not help.
Thanks in advance. -Saravanan
Attaching one such issue. (see how the terminal window is attached with the global title bar.
