Unity panel gets focus on minimizing a maximized window

[Loris Zinsou]

Binary package hint: unity

This is a bug in unity 3.4.6.

As with any window manager, when I minimize a maximized window, I expect the underlying to get focus.
In Unity, I expect the window controls and global menu to show up in the panel.

When I minimize a maximized window in Unity 3.4.6, the underlying window does not get focus, instead, the panel shows nothing.
If i click in the global menu place, I can see the Unity panel has focus because the menu shows up and i can quit Unity.

Three easy steps to make it happen :
1) Open a random application (i tried with Chromium, Libre Office, Gedit and the Console), maximize it or not has no incidence ;
2) Open another application(i tried Chromium, Gedit and Console too) and maximize it ;
3) Minimize it, and enjoy : the unity panel has focus, now you can quit Unity !
