Answer 1

The inner or lower title is the CSD -- Client-Side Decoration. What is supposed to happen is that the application tells the window manager not to put its own, standard, decoration, on the window. For some reason, in your situation, the window manager is ignoring that request and adding its own (outer/upper) title bar. Are you using a non-standard window manager, or have you inadvertently made some setting to the window manager, telling it always to decorate/reparent its windows?
