About the background color it is not a bug. The version 1.2.0 changed the background color and icon tint to support for enabled/disabled state in the FloatingActionButton.

From:

    <item name="backgroundTint">?attr/colorSecondary</item>
    <item name="tint">?attr/colorOnSecondary</item>

To:

    <item name="backgroundTint">@color/mtrl_fab_bg_color_selector</item>
    <item name="tint">@color/mtrl_fab_icon_text_color_selector</item>

You can check the selector:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:color="?attr/colorSecondary" android:state_enabled="true"/>
  <item android:alpha="0.12" android:color="?attr/colorOnSurface"/>
</selector>

The disabled state is based on colorOnSurface. In your case you are using the default value (#000000 with alpha=0.12)

I’ve submitted a PR to add the info about the states in the doc (#1619).
