Razer Blade QHD 2560x1440 scaling problem

Hi all, I got a problem with scaling of some apps - Steam, Battlenet and so on. Everything is fine with Windows, Chrome etc - it scales just perfect, but when I turn on for example Battlenet its just blurry. I have scaling up to 150% set in Windows - its just perfect for my eyes on 15,6 inch display. What can i do to scale other apps to the great resulution that my Blade offers? Thanks for all help.
