android - FAB - square on pre Lollipop and without shadow on Lollipop

Question

It looks like FloatingActionButton is not working ether on Android 4.0 and Lollipop. As you can see on image below, on Android Lollipopo shadow is missing and on Android 4.1.1 it's square :/

Anyone faced this issue?

Library version: compile 'com.android.support:design:22.2.0'

Code:

<android.support.design.widget.FloatingActionButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/abc_ic_clear_mtrl_alpha"/>

Thanks to @harism comment, simply setting app:borderWidth="0dp" resolve both issues.

Note: don't forget to add xmlns:app="http://schemas.android.com/apk/res-auto" to your root layout.
