If you have a shortbow, use Infiltrator’s Arrow. It immediately breaks stealth.
I am about 99% sure that this will show you as not being stealthed, yet your enemies will still see you stealthed, and the game engine thinks you are stealthed.
Anything that ports you does this, it is purely an asthetic bug.
If you arent sure, stealth up and use inf arrow, and look at buffs; or use it in a zerg of people and watch as they still dont attack:P
