firstly I'd like to thank you for this amazing addon.
Although I have been plagued by a strange problem.
Whenever I mouseover an item in my bags window i get big fps drop / stutter.

Disable your addon like bagsync etc.

All addons disable, only NDui

It is normal, it happens even you have all addons disabled.
Which only occurs when mouseover gear items, due to item info retrieving on Gametooltips.
