Game and Details! version
Details Version R7950
Game Version v9.0.1

Describe the bug
I just got the new Apple Mac mini with the Apple M1, and I'm testing some things out. The damage meter isn't working correctly... It appears like it is grouping all damage to the target under my single name. I turned off all Addons with this same result. See attached screen shot. I did this on a couple of training dummies but it was the same in a raid last night.

Oddly enough, as soon as I stop attacking and drop from combat, it looks like it starts adding the other players damage correctly. But things still seem off.

I don't know if this is an issue with the game and the M1, or related to how details processes information, or with details and the version of WoW for the M1. I tried Skada as well and it has the same problem it appears.

I had exactly the same problem with, also, my new mac mini with M1. And there were some problems with OmniCD as well. But yesterday both two addons worked smoothly again without any modification. So I think it should be some problems with in-game API(just like the pets collection problems), and they have been fixed through an inadvertently update/hotfix. You can try yourself and see if it is fine now in your case.
