FPS drop while scrolling through LFG dungeon tab

When I open the LFG dungeon tab and scroll through, there is a massive drop in FPS. I’ve checked and there doesn’t seem to be any other condition to trigger this. I have a similar problem in classic, when comparing weapons, but didn’t bother to make a ticket since it wasn’t a common event. Specs: Ryzen 9 5900x, Nvidia RTX 3080 with driver: 30.0.14.7111.
This issue just began today and it is persistent through game restarts.

I am having the same issue

RX 5700XT Ryzen 3600X
Corsair MP600 1t m.2 SSD
32gb 3200mhz RAM

checking now getting 1FPS when scrolling through players as well as Group Finder, maybe its raider.io issue? or new Blizz issue with retrieving character data in regards to IO and M+ scores?

FPS drop only happens then when scrolling with mouse wheel through LFG tool manually sliding down the scroll bar with mouse i remain at normal FPS.

This seems like the most likely cause. Unfortunately, Blizzard has no control over that addon.

@OP are you using that, as well?

they apparently fixed it now (blizzard) not raider.io
