Pixelated corners on carbon.widget.FrameLayout

[ildar2]

When I try to apply round corners on FrameLayout, they get edgy and pixelated. How to make them smooth?

           <carbon.widget.FrameLayout
                            android:layout_width="match_parent"
                            android:layout_height="wrap_content"
                            android:layout_marginBottom="24dp"
                            android:layout_marginLeft="16dp"
                            android:layout_marginRight="16dp"
                            android:layout_marginTop="28dp"
                            app:carbon_cornerRadius="5dp"
                            app:carbon_elevation="2dp">

That's interesting. What kind of device is this?

Device is Xiaomi 5A

Problem solved by adding
app:carbon_elevationShadowColor="@color/black"
and
android:background="@color/white"

Although if you add app:carbon_elevationShadowColor only, you'll get weird result:

I didn't notice that you don't have any background set. All the results you're getting are not bugs. The correct solution is to set background to any nontransparent color, because if the widget is transparent, the shadow can be seen through it. Changing shadow color will cause the widget to use alternate, software method of rendering shadows on Android 5.0+, so it's not recommended unless you really need colored shadows.
