Moto X (2014) :: Home Screen Redraw / Low Memory Since Lollipop Update

Noticed since the Lollipop update that if you spend some time in an app and then return to the home screen, it needs a second or two to redraw everything? It's like the phone isn't keeping the home screen in its memory.

The same for actual apps, too. Every single time I return to Chrome, it needs to reload the page. Or if I open, say Gmail, it's not as quick to open and needs an extra second or two to load up.

I was using Nova Launcher and switch to the stock Google Now launcher thinking it would solve the problem, but no dice.
