BottomSheetDialog background blinking

BottomSheetDialog's background is blinking when switching between apps. What am I doing wrong ?

BottomSheetDialog

MainActivity.java

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

findViewById(R.id.btn1).setOnClickListener(v -> {
BottomSheetDialog bottomSheetDialog = new BottomSheetDialog(MainActivity.this);
bottomSheetDialog.setContentView(R.layout.content);
bottomSheetDialog.show();
});
}
}


activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">

<Button
android:id="@+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />

</android.support.constraint.ConstraintLayout>


content.xml

android:layout_height="300dp"

The question is widely applicable to a large audience. A detailed canonical answer is required to address all the concerns.

Can you post your complete code of the activity and its xml

OnResume your bottom sheet is getting refreshed. You might want to check that.

@RoyalGriffin I have included my activity_main.xml also. This is the whole code I'm using right now.

I will investigate more, but my first impression is BottomSheetDialog class redraw the layout while pausing and starting. Time which is taken while pausing and starting it because of animation which BottomSheetDialog is having.
