Also, you mention 'wine-1.7.38' and 'wine-1.7.39' when the regression is in 'wine-1.7.40'. That intentional?
Yeah. For me 7a8ac888de232578dd36f799cf203e5a59fe5b70, which is in wine-1.7.40, fixes the lighting from the regression caused by 9811d85141610f903d6c8de3b00be6c853ece182 (i.e. random lighting of every object), which was merged before wine-1.7.39, and doesn't introduce any new visible regression.
Can you attach screenshots of what you see before and after 7a8ac888de232578dd36f799cf203e5a59fe5b70?
