Google launcher icons problem

Hey guys,

Please have a look at the screenshot from my OPO.
This happened just two weeks back.
All app icons in my phone started changing intro this rounded look.
I checked in other phones the icons are normal and transparent without the boxed icons.
I am on stock ROM cm13. No mods.
Using google launcher latest update.
I tried uninstalling, didn't help.

Thanks.
