    This issue was solved in 2.2.6. If updating doesn't solve, try using notifyItemRangeChanged(1, mDatas.size()) instead of notifyItemRangeChanged(0, mDatas.size()).

    If you're using notifyItemChanged(position) try changing it for notifyDataSetChanged(). This could be a bug with notifyItemChanged. Try dispatching all events as soon as they happen as well, since RecyclerView already bundles the updates by default.
