Loading image into imageButton in cardview leaves white space in cardview

Question

Issue:

I'm loading an image with glide and blur into a ImageButton inside a Relative layout inside a CardView. I've tried all the scale types but I can't make it work. The Relative layout is a must because I have other views inside that need to stack on the blurred image in some conditions. As you can see from the image below, there is a white space on the right side of the card view.

Question:

How to make the image fill the entire cardview while preserving the relative layout?

XML:

<androidx.cardview.widget.CardView

    xmlns:card_view="http://schemas.android.com/apk/res-auto"

        android:layout_width="174.75dp"
        android:layout_height="246dp">

        <ImageButton
            android:id="@+id/photoPlace"
            android:layout_width="match_parent"
            android:layout_height="match_parent"

            card_view:maxImageSize="17dp"
            card_view:srcCompat="@drawable/icon_eye" />

        <com.google.android.material.floatingactionbutton.FloatingActionButton
            android:id="@+id/btn2"

            android:layout_alignParentEnd="true"
            android:layout_alignParentBottom="true"
            android:layout_marginLeft="127dp"

            card_view:fabSize="mini"
            card_view:maxImageSize="17dp"
            card_view:srcCompat="@drawable/icon_heart" />

    </RelativeLayout>

</androidx.cardview.widget.CardView>

Glide:

Glide.with(activityContext).load(uri).transform(new BlurTransformation(100)).into(holder.photoPlace);

Please let me know if I should add anything else.
