I have fragment with recyclerview, then if i press 'home' btn and go to app again, i got that error

I unfortunately don't have time to look into this one, feels free to make a PR if you figure it out :)

@danielzeller i fixed this by changing updateMode to "onScroll" when im going to fragment with recyclerview. But when i go out from app, then go back i have gray colored layout instead of blur
