Android Lollipop éléments partagés transition clignotement / flash

Je vois une chose étrange dans ma transition d'élément partagé sur Lollipop. Les éléments partagés scintillent juste avant de commencer à s'animer (voir la vidéo https://www.youtube.com/watch?v=DCoyyC_S-9A )

Je ne sais pas pourquoi cela se produit. Cependant, lorsque j'ajoute <item name="Android:windowSharedElementsUseOverlay">false</item> à mon thème, je ne vois pas de scintillement mais la transition ne semble pas bonne (on dirait que seulement la moitié de celle-ci anime la seconde moitié de l'animation "cachée").

Autres paramètres de transition:

<item name="Android:windowActivityTransitions">true</item>
<item name="Android:windowContentTransitions">true</item>
<item name="Android:windowAllowEnterTransitionOverlap">true</item>
<item name="Android:windowAllowReturnTransitionOverlap">true</item>
<item name="Android:windowSharedElementEnterTransition">@Android:transition/move</item>
<item name="Android:windowSharedElementExitTransition">@Android:transition/move</item>

Je commence une activité en utilisant ActivityCompat et ActivityOptionsCompat:

ActivityOptionsCompat options = ActivityOptionsCompat.makeSceneTransitionAnimation(ActivityMain.this,
                        new Pair<View, String>(playButton, getString(R.string.translation_control_button)),
                        new Pair<View, String>(findViewById(R.id.playerImage), getString(R.string.translation_artwork)));

ActivityCompat.startActivity(this, pendingIntent, options.toBundle());

Avez-vous une idée de pourquoi cela se produit?

Hourra! J'ai réussi à résoudre ce problème.

L'écran clignotant est un problème commun décrit ici: écran clignotant sur la transition d'image entre les activités (thx @AlexLockwood)

L'élément partagé clignotant a été provoqué par DrawerLayout. Je commençais bientôt une nouvelle activité. Lorsque j'ai déplacé ActivityCompat.startActivity Vers la méthode onDrawerClosed de DrawerLayout.DrawerListener, Tout a commencé à fonctionner comme un charme.
