Might be related to this issue also reported on PBE: [link](http://boards.pbe.leagueoflegends.com/en/c/bugs/cKz5OkEA-kogmaw-portraiticon-is-a-blue-square)
In a game of hexakill today I noticed Azir's turret health was shown with a blue rectangle, not unlike the Kog'maw issue reported above.
Not sure of steps to recreate, but here are the observations:
- Azir skin: Galactic
- Outer turret
Attached is a screenshot.
