What is this?

I asked around on the ESO forums and was given the impression this was an addon error, which I assumed, or everyone and their dog would be griping about it. Even got a moderator response where he suggested it was an 'orange moustache'! Then he said if it wasn't from the vanilla game they couldn't provide support for it, so he didn't seem to know what it was either...

Can't say I ever saw something like that.

Have you tried disabling all the Addons and reloadin the UI? If it was an addon, it should vanish.
Have you made a repair scan of the client?
What exactly do you do before that appears? Is it just there after every login?

It looks a lot like the frame for boss healthbars. Do you have addons installed, that modify healthbars?

[CrazyDutchGuy]

It is the frame that goes on both sides of the health bars. Well at least part of it. Only option to verify is to disable all yur addons and see if problem still exists.

its an addon causing it i have the same issue every time i log in or reload ... i had figured out what addon was causeing it but i completely forget now lol ill update if i remember lol

[pinstripesc]

Haha.

Yeah, I was thinking it looked a lot like the frame you get on bosses, only glowy. Someone else suggested that too. I do use a lot of addons (38 atm) and that's definitely the cause, I never really attributed it to an ESO bug. It shows up when I first log into the character and sort of faintly glows in and out, but it disappears after about 10 seconds then never comes back. Someone said there's disappeared as soon as they targeted something with health.

Honestly it's not that big of a deal but it's been there forever and I'm just trying to figure out where it came from! Someone suggested disabling Combat Indicator, which I'm gonna try. I could go through all my other addons 1 by 1 but that'd take..forever

I have repaired the client since it started, I've had it for like 2 months. I'll test it soon here to see if it disappears with everything disabled.

Here's what I'm using atm -

PL_CombatIndicator"
pNames"
questBuddy"
SimpleHelmetToggle"
SkyShards"
SoftcapInfo"
SpentSkillPoints"
Srendarr"
Stacked"

I've highlighted the ones I would think might have anything to do with it, I dunno how most of those others could touch that sorta thing. I did think it was Azurah when it first happened and asked the author, but he didn't know what it was, and someone else on the official forums also said they used Azurah but it didn't seem to be the cause.
