GIF glitchy rendering with RoundedCorners in Glide 4.2

With this layout:

<FrameLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="@dimen/media_bubble_height"
        android:layout_height="@dimen/media_bubble_height"
        android:layout_marginBottom="5dp"
        android:layout_gravity="center"
        android:scaleType="centerCrop"
        android:adjustViewBounds="true">

    <ImageView android:id="@+id/image"
               android:layout_width="match_parent"
               android:layout_height="match_parent"
               android:adjustViewBounds="true"
               android:clickable="false"
               android:longClickable="false"
               android:scaleType="fitCenter"/>

</FrameLayout>

Loading a gif into the ImageView:

    GlideApp.with(getContext())
            .load(model)
            .diskCacheStrategy(DiskCacheStrategy.NONE)
            .transform(new RoundedCorners(radius))
            .transition(withCrossFade())
            .into(image);

Consistently produces these glitches in Glide 4.2.0:

Happens for every gif I try, here's a sample:

In Glide 3.7 I used a custom RoundedCorners transformation (I don't think one came with Glide?) and this wasn't an issue.

Glide Version: 4.2.0

Does the old custom one you used with 3.7 cause these glitches as well? Or just the built in one in Glide?

Looks like #2345

The old custom one I used with 3.7 worked fine. I'm working on upgrading to 4.x to see if that resolves #2453, but I'm having problems with this and gif playback speed.

Here's a small standalone project that reproduces these glitches:

Thanks for the sample app, hugely helpful!
