FPS tanks whenever I mouseover a mob

[Aerenne]

Alright, I usually have around 140-160 FPS at all times, but now whenever I am not in combat and my cursor goes over a frame, mob, or anything that you can click on, my FPS drops to around 12. But when I am in combat, I can mouse over Grid without my FPS failing, but nothing else. Does anyone know what is wrong?

Some extra stuff -

I play with all settings at maximum, the problem persists even with everything at minimum.

I have tried enabling and disabling verticle sync, still having problems either way.

there are many addons that modify your mouseover tooltips, so it can only be that.

either update all your addons, or try to find out which one it is

What tooltip addon are you using? If it's Cowtip, I suggest changing to something else, due to the base libraries being so bad that their author doesn't even write addons to use them anymore. I prefer Tiptac, personally.

Actually, it just... randomly fixed out of nowhere. Had this problem for almost a month, and it randomly fixed... No idea why. I use tiptac btw.
