Shadow displaying as square on FloatingActionButton Glide V4

I recently upgraded Glide to version 4 which has caused problems with the image I display in a floating action button. I have attempted 2 methods and I use the same XML for both:

XML:

<android.support.design.widget.FloatingActionButton
    android:id="@+id/profilepic_fab"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:scaleType="center"
    app:layout_anchor="@id/appbar"
    app:layout_anchorGravity="bottom|center_horizontal"
    app:srcCompat="@mipmap/bookmark_checked_white" />

Method #1:

            RequestOptions optionsCentre = new RequestOptions()
                    .placeholder(R.drawable.profilepic_placeholder)
                    error(R.drawable.profilepic_placeholder).dontTransform()
                    .dontAnimate().CircleCrop();

            Glide.with(context)
                    .load(userinfo.getprofilePic())
                    .apply(optionsCentre)
                    .into(profilepic);

Result of Method #1: It looks good on Android 7.1.2 but on 4.4 it looks like the image below:

Method #2:

RequestOptions options = new RequestOptions()
                .fitCenter()
                .placeholder(R.drawable.profilepic_placeholder)
                .error(R.drawable.profilepic_placeholder)
                .priority(Priority.HIGH);

    Glide.with(context)
            .asBitmap()
            .apply(options)
            .load(url)
            .into(new BitmapImageViewTarget(fab) {
                @Override
                protected void setResource(Bitmap resource) {
                    RoundedBitmapDrawable circularBitmapDrawable =
                            RoundedBitmapDrawableFactory.create(context.getResources(), resource);
                    circularBitmapDrawable.setCircular(true);
                    fab.setImageDrawable(circularBitmapDrawable);
                }
            });

Result of Method #2: The results look different on Android 7.1.2 and 4.4

Android 7.1.2:

Android 4.4:

Method #2 is what used to work with Glide v3... Any help would be greatly appreciated!
