Describe the bug

Loading into the game, looting a kill, or interacting with vendors all cause major lag - it's easily visible by the stutter in movement of npcs, mounts, etc.

I've turned off every addon and the game works fine. I've gone through every other addon one by one. I've seen similar looting issues mentioned on the WoW forums, so I've played around and removed BB from my addon folders, removed everything except BB, done a fresh install of BB, etc. and it is most definitely BB causing the issue for me.

Also, using any BB plugins from the smaller Tabards to the larger AIO (All In One) makes the effect worse. Last night I clicked on a vendor and the game actually crashed. That's when I finally decided to narrow down the culprit.

I'm not getting any warnings or anything from wow.

I've added a small edited clip with BB off and then on. This is just the minimal amount of stutter, it gets worse when looting a lot (dungeons, delves, etc), or if you start using plugins with it.

I'm not smart enough when it comes to addons to figure out why it's happening. :(

Steps to reproduce

Load game.
Click on vendor - it lags.
Close vendor - lags.

Kill something (any level) and loot - lag.

Enable a bb plugin - lag becomes worse. (The AIO plugin is the worst of the ones I've used and I'm also going to let the creator know, but this happens even with all plugins not just disabled but straight up deleted from the addon folder.)
Disable bb plugin - still lags, but recovers faster.
