Thanks for that.
You only just filed this bug, so I’ve no news to share yet.
It looks like the CodeWeavers’ folks did a bunch of research into this. Do you know if they filed a bug about it?

CodeWeavers already had an open bug for OverWatch 2, that same bug also affects Diablo2:Resurrected
I‘m also aware of another Rosetta2 bug they have open that affects legacy WoW clients.
Do you have FBnnn numbers for any of those?
