Not sure if this has been reported yet but just got to Act 2 and doors/map transition icons and non-companion NPCs are disappearing regularly. Sometimes when entering a new area from world map the screen is entirely black (still able to access menu and see highlights of characters, but otherwise completely black).
Only work around I’ve found is completely shutting down game and reopening it.
On XBOX Series X.
