How do I get the Amazon fire tv stick away?

I only pause for a few minutes (netflix) and then this window comes up, how do I remove it or deactivate it?

Either switch off the screen saver in the menu or upload your own pictures to the Amazon Cloud and use them as a screen saver.

Take the default screensaver. As soon as you end the break, it will go away immediately.

Take the standard screensaver, they are there so that when you press pause, the picture doesn't burn into your TV. So it's something you should start with.
