@Preview(showBackground = true)

    ModifierLayoutDrawing()

fun Modifier.moveDraw(): Modifier {
    return layout { measurable, constraints ->
        val place = measurable.measure(constraints = constraints)

        layout(constraints.maxWidth, constraints.maxHeight) {
            place.placeRelative(100, 0)
        }
    }
}

Try to remove the moveDraw modifier, see if that interferes with the whole canvas. Could be that you are moving everything.
