Blue defense bar

Yea with that pic zooming in would help. In game on a phone it is very obvious. And again it only happened mid fight and after the enemies healed back to full protection. then I hit them and it goes back to light blue. So it could be a graphics issue but I would think it would stay white for those 2 people for the whole fight but logic doesnt always apply to glitches.

Figured someone would have seen the same thing before and say its a known bug or that I just didnt understand an ability or something.
