Confusing issue / Crystallized Homescreen

[Clemenson]

I'm faced with a serious issue here on my iPhone 6s Plus 128GB (Screenshot attached). That's the second iPhone (swap at Apple Genius Bar) that shows the same visual error. Since day one, I'm always setting it as a fresh new iPhone without any backup/restore. Currently I'm running iOS 9.1. I'm facing the error occasionally and occurs when I swipe down the Spotlight/Search, the homescreen crystallizes and is broken down to pixels. Therefore I assume it's a software problem, waiting to be fixed. My iPhone initially was one of the first, pre-ordered together with a phone contract in Germany.

I kindly ask everybody for troubleshoot, feedback, idea or a known method to fix it.

Thanks.

I had this on my iphone 5s, 6 and 6s. Definitely software but not a big deal.

Mine seems fine. But lag when opening it.

Happened to me for the first time today. After turning my phone off and on, it seems that problem is solved.. for now.
