Android full screen navigation bar transparency bleeds onto navigation view

Question

I'm using design library navigation view in full screen. But transparency of Navigation Bar and Status Bar bleeds onto NavigationView.Transparent black rectangles occur on right and top of the NavigationView.

My Layout

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <include
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        layout="@layout/layout_custom_view" />
</RelativeLayout>

<!-- Navigation View -->

<android.support.design.widget.NavigationView
    android:id="@+id/navigation_view"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    app:headerLayout="@layout/navigation_view_header"
    app:menu="@menu/navigation_menu" />

MainActivity.java

    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    if (Build.VERSION.SDK_INT < 16) {
        getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
    } else {
        hideSystemUI();
    }
    setContentView(R.layout.activity_main);

    // Set NavigationView with Header and Menu
    setNavigationView();
}

/*

/**
 * Hide Status and Navigation bars
 */
public void hideSystemUI() {
    if (Build.VERSION.SDK_INT >= 16) {
        View decorView = getWindow().getDecorView();
        // Hide both the navigation bar and the status bar.
        // SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and
        // higher, but as
        // a general rule, you should design your app to hide the status bar
        // whenever you
        // hide the navigation bar.
        decorView.setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                // Views can use nav bar space if set
                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION 
                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                // hide nav bar
                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                // hide status bar
                | View.SYSTEM_UI_FLAG_FULLSCREEN 
                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
                );
    }

}

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    if (hasFocus) {
        hideSystemUI();
    }
}

Removing View.SYSTEM_UI_FLAG_LAYOUT_STABLE solves the issue.
