[Wine] Screen dims when running a game

[Decollete]

Hello. I just installed Wine and tried running a game. When the game screen launches, even if it is not full-screen, my entire screen dims. This includes the actual screen outside of the game screen. I think this is just the default behavior.

Is there a way to disable dimming the screen? Or, is it possible to make it affect the window running Wine only and not the entire display?

Thanks!
