возникли проблемы при установке animateLayoutChanges true на ConstraintLayout

Question

Я использую ConstraintLayout в качестве родительского макета и set android:animateLayoutChanges="true". при изменении видимости некоторых вложенных видов показывается мой слой (androidx.constraintlayout.helper.widget.Layer), который я использовал в качестве фона других представлений. без android: animateLayoutChanges все в порядке.

Я также попытался requestLaout() в методе post() виджета Группы (относится к некоторому вложенному представлению для действия show / hide) -> group.post { binding.bg.parent.requestLayout() }, и это работает. но этот способ показывает слой через короткое время, и я не хочу, чтобы это происходило.

вот мой XML-файл:
