I can only seem to reproduce this when I have "General Options->Focus & Raise Behavior->Click To Focus" unchecked.
I believe this is a Compiz issue and was probably introduced when I tried to handle the Gtk X input stuff introduced in 14.04, which has been a total pain.
I'll give it a look and see if I can come up with a solution for this without breaking everything else.
