Stop rendering when the window is not visible.

So I like this terminal while playing some very old terminal video games like in bsdgames, however, I tend to keep this terminal open when I'm not doing anything which uses up some power from GPU and my laptop's battery.

This app should have an option to stop rendering when the window is not visible in order to save battery power and fan speed.
