So I have just started using the screen saver feature and everything was working properly. I am using the Bubbles screen saver and today for the first time when I left it for about 30min. When I came back it was freaking out and the bubbles were moving super fast all over the place. Is this just happening to me or anyone else is this supposed to happen or is this just a bug?

Yes it does, I turned it on 4 different times in like 2 hours and everytime when I came back it was doing it. So for the fifth time I watched it as it was happening it goes normal for like 20min then just out of no where turn into the speedy mess. What I think might be happening is its adding to many bubbles on the screen. I put it same saver on another screen and it happen at a different time as well. The second screen it had like an extra minute before it started to freak out. So I don't think it is related to the amount of time.
