When I set "Show Tips" to Daily or Never, new tabs won't let me start typing unless I click in the window. If I alt-tab away and back it still doesn't work, so it appears it isn't just a focus issue. It requires a mouse click in the active window or tab before I can start typing in the terminal. When I set it back to "Show Tips: Everytime" I can open new tabs using the keyboard shortcut and start typing immediately.

I'm using Ubuntu 16.10.
