View Apps In Background As "screenshot"

Jan 16, 2016
Hi to everyone!

I have changed my ROM from the Weekly 6.2.25 to the stable 7.2 for my Redmi Note 2. So far, the ROM is running well. The only thing that disturbs me is the fact that in the 6.2.25, when I was hitting the "background button" (bottom left), there was an overview of the running apps with a screenshot on it. Now on the stable one, only the icons of the apps are shown.

Is there any way to change the icons and put the screenshots back?
