Undesirable white background behind the FAB

[praina]

First of all, thank you for this library it is a great one.

Now on to the bug.
There is an unnecessary white background coming behind the FAB and it is also blocking the background of the buttons.

Expected result

I expected the FAB with a group of buttons as shown in the gif, I am getting the buttons but I am also getting undesirable white background which is obstructing the other view.

Can you confirm this only happens in >=N?

I am using Marshmallow in my mobile device so it has to be a case for <N as well. No idea how it will work on pre-Marshmallow devices.

Well, I'm not able to reproduce this... I've tinted my sample app with a black background and everything looks fine.

You should investigate you XML, re-open this issue if required.
