I can't open your image and see the actual leak but if you define a local variable for your RecyclerView in your Fragment and set your fragment's retainInstanceState true it can cause possible leaks with rotation.

When using a Fragment with retainInstance you should clear all your ui references in onDestroyView

@Override
public void onDestroyView() {
     yourRecyclerView = null;
     super.onDestroyView();
}

Here you can find a detailed information from this link: Retained Fragments with UI and memory leaks
