New OS and hardware. New error.
I just had the unfortunate experience of doing a fresh install of Windows 10 Pro on new hardware and I been trying to get everything back to normal. I think I have ESO working normally for the most part except for one mysterious UI error that isn't giving me a clue as to the source.

Anyone have any idea what the cause of this is? It seems to only pop up when loading in or doing a /reloadui and otherwise I haven't noticed any issues.
