--- Comment #7 from RĂ©mi Bernon rbernon@codeweavers.com --- The game window has some invisible child windows, and it triggers the offscreen window rendering, which somehow is broken in this case (not completely surprising, offscreen windows were actually known to be bogus, although it worked in other cases).
With https://gitlab.winehq.org/wine/wine/-/merge_requests/6998 things should get back to normal and the intro video plays fine for me.
