Answer 1

credo che appare quando v'è ancora una barra del titolo. Ho appena nascosto la barra del titolo e funziona bene ..

dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE); 

Answer 2

Usa questo cambia:

sul DialogFragment:

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

    setStyle(android.support.v4.app.DialogFragment.STYLE_NO_FRAME, R.style.my_dialog_style); 
} 

sul tuo stile R.style.my_dialog_style aggiungi il seguente:

<item name="android:windowContentOverlay">@null</item>
