Android Distorted UI

I am not able to find the root cause of the below distortion.
UI works fine but when I rotate the screen to landscape, the UI gets distorted while scrolling.
This distortion continues when the screen is again rotated to portrait.

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="8dp">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <include layout="@layout/i_details" />

        <include layout="@layout/v_details" />

        <include layout="@layout/d_details" />
    </LinearLayout>


</ScrollView>

UPDATE 3
added activity code and stated fragment logic


i_activity

public class MYActivity extends AppCompatActivity {
    private static final String LOG_TAG = MYActivity.class.getSimpleName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_invitation);

        MYFragment myFragment = new MYFragment();

        // In case this activity was started with special instructions from an
        // Intent, pass the Intent's extras to the fragment as arguments
        myFragment.setArguments(getIntent().getExtras());

        // Add the fragment to the 'my_container' FrameLayout
        getSupportFragmentManager().beginTransaction().add(R.id.my_container, myFragment).commit();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        recreate();
    }
}


in Fragment, I fetch the ID passed from activity, populate my static UI,
initiate CURSOR LOADER

@Override
    public void onActivityCreated(Bundle savedInstanceState) {
        Log.d(LOG_TAG, "Activity Created");
        getLoaderManager().initLoader(CURSOR_LOADER, getArguments(), this);
        super.onActivityCreated(savedInstanceState);
    }

and
onLoadFinished(Loader loader, Cursor cursor)
fetch and populate my dynamic UI views directly.
Not using any adapter as all views are simple text views.

Included layouts are simple layouts with LinearLayout as parent container and FrameLayout or LinearLayout as the child and other views.

I am using Picasso lib to load the static map.
UPDATE 2 Picasso is not the issue as after removing Picasso, the issue remains.

The problem is your Fragment is created Twice on the orientation Change Check saveInstancestate before creating new Fragment Object.

private MYFragment myfragment;//define fragment globally

  if(savedInstanceState == null) {
       myfragment= new MYFragment();//set tag for fragment
       getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, headlines, FRAGMENT_TAG_STRING).commit(); // Use tags, it's simpler to deal with

    } else {
        myfragment= getSupportFragmentManager().findFragmentByTag(FRAGMENT_TAG_STRING);
    }
