Shine is not working when removing the status bar

I'm trying to remove the status bar. The shine effect doesn't work after implementing the following code:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
val w: Window = window // in Activity's onCreate() for instance
w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)
}
