Shared Transition Animation Glitch

What I Have

I have set the permission correctly.

<item name="android:windowContentTransitions">true</item>        
<item name="android:windowAllowEnterTransitionOverlap">true</item>
<item name="android:windowAllowReturnTransitionOverlap">true</item>

<!-- specify shared element transitions -->
<item name="android:windowSharedElementEnterTransition">
    @transition/change_image_transform</item>
<item name="android:windowSharedElementExitTransition">
    @transition/change_image_transform</item>

And this is my transition file,

<transitionSet xmlns:android="http://schemas.android.com/apk/res/android">
    <changeImageTransform/>
    <changeBounds/>
    <changeTransform/>
</transitionSet>

Now, in my master activity, I gave a GridView with image thumbnails. 

View photo = (View) list.getChildAt(position).findViewById(R.id.fileThumb);
                    photo.setTransitionName("photo" + position);
                    ActivityOptions options = ActivityOptions.makeSceneTransitionAnimation(getActivity(), Pair.create(photo, photo.getTransitionName()));

                    Intent intent = new Intent(getActivity(), GalleryActivity.class);
                    intent.putExtra(Config.GALLERY_EXTRA, position);
                    getActivity().startActivity(intent, options.toBundle());

In my Detail activity,

I have a ViewPager with a fragments. In the onCreate() of the fragment, I did this.

final PhotoView photoView = new PhotoView(container.getContext());
                    relativeLayout.addView(photoView, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
photoView.setTransitionName("position"+pos);

The animation seems to work on the correct items, but not smoothly. There seems to be a glitch in the animation. However, the exit transition is somewhat smooth. But still not perfect.

What am I doing wrong here?

Are you using the PhotoView library by Chris Banes? If so, it's not yout fault but a bug in the library: https://github.com/chrisbanes/PhotoView/issues/243
