Artifacts when using AnimatorSet with CardView on Android 5-6

With the help of animation I turn the map over. The animation of the map passes correctly, but in the background and around there are some dark shadows or a dark vertical bar. On Android 4, it works properly. If you use LinerLayout instead of CardView works CardView . What could be the reason?

 CardView imgFront = (CardView) view.findViewById(R.id.card_1); CardView imgBack = (CardView) view.findViewById(R.id.card_0); AnimatorSet setRightOut = (AnimatorSet) AnimatorInflater.loadAnimator(getApplicationContext(), R.animator.flight_right_out); AnimatorSet setLeftIn = (AnimatorSet) AnimatorInflater.loadAnimator(getApplicationContext(), R.animator.flight_left_in); if (!isBackVisible) { setRightOut.setTarget(imgFront); setLeftIn.setTarget(imgBack); setRightOut.start(); setLeftIn.start(); isBackVisible = true; } else { setRightOut.setTarget(imgBack); setLeftIn.setTarget(imgFront); setRightOut.start(); setLeftIn.start(); isBackVisible = false; }
