Thanks, i had a look around the options on fortexorcist, but the only thing i could find was "Enable Secondary Splash Icon" which was already disabled.
When i enable it, i get an icon in the centre of the screen but its icon.
I'll have to agree with Taryble here, it looks like it might be ForteXorcist (at least, none of the other addons seem any likely). I'd suggest disabling it to see if that's where the problem lies. If not, disabling the rest of the addons one by one would most likely work in identifying the addon, cumbersome as it might be. Good luck!
Or use the 50/50 method for it - disable 50% of your addons, reloadui. If the problem goes away, it was one of those addons. Enable half of them. Reloadui. If the problem didn't go away, then it was one of the addons you left on - disable those, enable the other half, reloadui. The problem is gone. Now enable half of the disabled addons, then reloadui. Continue ad nauseam until you get it down to 1 addon.
