Sorry for the late reply, my wife just recently gave birth to our twins. No, I am playing on Windows 10. I did see the resolution auto fix itself as well.
Just got the game, and have to say I am pretty excited to check the game out! I was wondering are you going to add support for Ultrawide 21:9 Monitors? 2560x1080? That's my main and I don't mind the black bars, but they do take away from the game.
