Unity 7.4 - bug - unable to interact with windows after some time

[v]

After period of time (couple of days?) I am unable to interact with windows. As far as I can tell at this point it only affects Gnome Terminal 3.18.3.

Not sure if there is way to reproduce this issue, except just have the terminal windows open for couple of days.
I lost the ability to resize the window, or interact with maximize, minimize, or close button.
Top Menu still works. I can still type in commands into the terminal.
The mouse pointer never changes from I to mouse pointer when hovering over the control bar.
Clicking on the control bar minimizes window, instead of focusing the window.
Resetting the terminal does not fix the issue.
The only way to fix the issue is to "exit" Gnome Terminal using exit command.

Anyone else having same issues?
