This is a pretty weird but severe bug. It seems to happen a bit randomly when it triggers but then stays until restart of game. I can disable and enable addon and the bug still stays. Full addon reload ui also resets it.

This is my game with all RealUI addons turned on execpt "NibRealUI" 153 frames which is average and what I want for my 144hz monitor.
I enable "NibRealUI" back on and this

suddenly drop of 70 frames. Sometimes it's been 45ish frames sometimes 30. My CPU usage and GPU usage are not maxed but really low with WoW only using like 20-40%.

This is memory usage and CPU usage, I swapped to economy mode and nothing changed. Strangest thing is that even if I have 70 frames with UI enabled I instantly go up to my normal 145 frames if I hide my UI with Alt+Z so it's clearly something with the UI that is doing something weird.
