Making everything behind the app blurry?

I can access the image behind my app. But it doesn’t blur it. For example: I have a panel on the bottom layer and by making it a little transparent I can get the view behind the application. But when I add the blur shader to that panel, it shows the background as black. My question is, how do I make the background blurry without making it black?
