Description

When opening Screen A, everything is fine. 3 static rows with a single text line each are shown.
When opening Screen B, a list with multiple rows, containing multiple lines are shown.
Closing this screen, we return to Screen A. It looks okay for some time, but then after 100-500 ms, it breaks.

With Android Auto 9.0 and higher, on both the DHU and a real head unit, the UI begins to glitch out then. The item rows are combined somehow. This is reproducible 9 to 10 out of 10 times. After some seconds, it fixes itself.

Is it our code that is causing this?

Well, I hope not :D We are calling invalidate() 3 times on Screen A. Even if commented out, this bug keeps reproducing. We have never had an issue like this, and only since 9.x this is occurring.

Screens A and B are both using PlaceListMapTemplate.

We are building Screen A's rows like this:

    private fun createRowForScreen(
        @StringRes titleId: Int,
        @DrawableRes drawableId: Int,
        onClick: () -> Unit,
    ): Row {
        val image = CarIcon.Builder(IconCompat.createWithResource(carContext, drawableId))
            .setTint(CarColor.PRIMARY)
            .build()

        return Row.Builder()
            .setImage(image)
            .setTitle(lokaliseResources.getString(titleId))
            .setBrowsable(true)
            .setOnClickListener(onClick)
            .build()
    }
