i don't think its nui
 

I am like the only one atm who uses nUI in my guild. But we are all having the same glitchy issues. I realized last night that the fps murderer in raid wasn't nUI, it was Recount. I had to pause data collection. Chat issues, everyone is having those, some links are clickable and some don't seem to work. Yey! Blizzard patched new content and once again screwed up the stuff that was working just fine before.
