I was just informed that FB21763885 might be more detailed and more easily reproducible.

That would be FB15880492 I this now also affects Diablo 4 Test Realm/ that version might now be live with the Diablo 30th anniversary updates landing for both Diablo 4 & Diablo 2

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.
