application style only affects current windows in plasma

I set application style to breeze. But then when I open another application, even like Dolphin or Kinfocenter, it uses some dark application style. I work around this by setting --style=Breeze in the .desktop icon in the menu, but I want a global solution and not all apps have the --style setting.

Also, if I unset environmental value QT_STYLE_OVERRIDE and export QT_QPA_PLATFORMTHEME=qt5ct it works fine but only if I open the applications with command line.

How would I set this for "global" use?
