First off I would like to thank ckknight for an awesome mod, great work so far.
I am having a problem in raids with stuttering while in combat. I do not use the raid frames, only target and target of target. If I am not targeting the mob i have no stuttering, but as soon as I target a mob it starts up. I believe that I have narrowed it down to the aura system on the target frame. I have it set to show all 40 debuffs, sort is OFF, snap is ON, filtering is OFF, split is OFF, highlight is ON for debuffs. When I disable the aura system for the target frame the stuttering goes away. I have tried various combinations of settings to find the exact culprit however totally disabling the aura system is the only way I have found to stop the stutter. I really like Pitbull but I am forced to use ag_uf while raiding because I need to see debuffs and I can't get playable performance with Pitbull.
