I see strange thing in my shared element transition on Lollipop. Shared elements are flickering just before they are starting to animate (please see video https://www.youtube.com/watch?v=DCoyyC_S-9A)
I've no idea why it is happening. However when I add <item name="android:windowSharedElementsUseOverlay">false</item> to my theme I don't see flickering but the transition is not looking good (they look like only half of it is animating second half of animation 'hidden').
Other transition settings:
<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>
I am starting activity using ActivityCompat & 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());

Do you have any ideas why it is happening?

Hurray! I've managed to solve this problem.
Blinking screen is common problem described here: Blinking screen on image transition between activities (thx @AlexLockwood)
Blinking shared element was caused by DrawerLayout. I was starting new Activity to soon. When I've moved ActivityCompat.startActivity to DrawerLayout.DrawerListener's onDrawerClosed method everything started working like a charm.
