Omen oddities

[Orb]

Ever since I have begun using nUI, I've noticed that the Omen threat bars are extremely jumpy. They used to be rather fluid in the way the bars updated/reacted, etc, but now the threat bars seem to jump all over the place, and makes it difficult to see where I actually am in comparison to others.

Has anyone else had these similar issues? Is there a setting in Omen that I'm missing?

Thanks
