From an internal mail conversation titled "Terminal is always ticking":

I notice that Terminal on my machine is constantly ticking, meaning XAML Tick. It looks like there is a DispatcherTimer constantly running, even when the app isn't in the foreground and even when it is minimized.

We should stop any DispatchTimers when Terminal is minimized.

May also want to refer to #1989 while we're at it. Conhost (I believe) stopped rendering when minimized, but I'm not sure Terminal is hooked up to know [A] when the window is minimized, and [B] when a TermControl is or is not part of the visual tree.
