Windows do not respect the Unity top-bar

[hexafraction]

On a new Trusty installation, many windows trying to open at what apparently is a default position of the top screen (this happening with multiple applications, including Firefox), end up placing their title bars directly under the Unity top bar. This causes the window to be immovable without the use of [alt]+[space].

Often this occurs with older, non-Unity-aware applications, as well as Firefox popup windows (the screenshot popups on appdb.winehq.org being one example).

I've not reconfigured Firefox beyond setting a home-page, and have not used any sort of compiz or Unity tweaking package.

I would expect either the window to be moved downward to avoid the overlap, or for the topbar to convert to the menubar (as is seen when windows are maximised).
