--- Comment #34 from Sergey Isakov isakov-sl@bk.ru --- Testing many wine versions with or without staging patches and patches found on the bugzilla. Result is mostly always the same with some additional bugs. This bug remains to be the last stop to play the game. The darkness is happen on the company of Captain Craig and sometimes on other scenes. And always on the same place. Now I checked other battle and see very good colors. Return to Captain save and see bad colors again. Reloading resources doesn't help.
My game is from purchased DVD: Might & Magic Heroes VI Shades of Darkness 2.1.0. I also have previous edition Heroes VI Gold Edition and it has no such bug. It has a bug with increasing lags as well as on Windows. SoD works fine on Windows 7.
My system is macOS 10.13.6 with Xcode10,1. Wine compiled with SDK10.11 and numerous MacPort libraries like libpng, libtls etc. Nvidia GTX650 + hidden Intel HD530. I have to mention it because Wine see it as well. I will attach good screenshot for just other scenario but with the same wine. Some minutes later a log with DEBUG.
