In my PlayerSettings I have the Default Screen Width set to 1280 and the Default Screen height set to 720. When I build the project the player launches in 1920x1080 and sets the width/height registry value to 1920x1080. This was working all fine and dandy before updating to Unity 2017.2 (wow!). It's also worth nothing that my builds are also creating a 22MB 'UnityPlayer.dll' file on my Desktop which was not happening before updating to 2017.2 and I'm thinking this may have something to do with it. Any suggestions?
