I have started using motion layout for some top bar scrolling, and looks like there is an issue that prevents recycler view from showing updated data. Currently I am using 2.0.0-alpha3 of ConstraintLayout. In the view I have toolbar and 2 tabs that act as filter, lets say filterX and filterY those pass some rx stuff that basically just filters list of items based on the type this is not important because data is filtered properly, thread is correct, data is passed to adapter every time, but when I do scroll my motion layout to top or bottom, from time to time the changes are not reflected in recycler view, they reload after I scroll it a little bit or even touch, its not happening in case of standard ConstraitLayout. Have anyone experienced this and know any solution?
Edit: Layout with motion layout:
<androidx.constraintlayout.motion.widget.MotionLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layoutDescription="@xml/scene_month">
<androidx.appcompat.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:navigationIcon="@drawable/ic_back"/>
<TextView
android:id="@+id/title"
style="@style/ActivityTitle"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@id/toolbar" />
<com.example.FilterView
android:id='@+id/filter_view'
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@android:color/white"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@id/title"/>
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/recycler"
android:layout_width="0dp"
android:layout_height="0dp"
android:clipToPadding="false"
android:paddingBottom="16dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"

app:layout_constraintTop_toBottomOf="@id/filter_view" />
</androidx.constraintlayout.motion.widget.MotionLayout>
