Component used: wear-compose, TimeText Version used: Alpha-20 Devices/Android versions reproduced on: Square Emulator, Round emulator

I can provide a repro in a private repro on request. I understand this isn't very useful here.

Or given a few days I can make a standalone reprod.

A custom Time text like

    val state: NetworkStatusAppState by rememberStateWithLifecycle(viewModel.state)
...
                // TODO investigate why this is needed
//                key(state.dataUsage) {
                    DataUsageTimeText(
                        modifier = it,
                        showData = state.showData,
                        networkStatus = state.networks,
                        networkUsage = state.dataUsage
                    )
//                }

state is a data class.

eventually these call components for startCurvedContent and startLinearContent

    TimeText(
        modifier = modifier,
        startCurvedContent = {
            curveDataUsage(
                networkStatus = networkStatus,
                networkUsage = networkUsage,
                style = style,
                context = context
            )
        },
        startLinearContent = {
            LinearDataUsage(
                networkStatus = networkStatus,
                networkUsage = networkUsage,
                style = MaterialTheme.typography.caption1,
                context = context
            )
        }
    )

fun CurvedScope.curveDataUsage(
    modifier: Modifier = Modifier,
    networkStatus: Networks,
    networkUsage: DataUsageReport?,
    style: CurvedTextStyle,
    context: Context,
) {
...
        val usage = networkUsage?.dataByType?.get(activeNetwork.type.typeName)
        if (usage != null) {
            curvedText(
                text = usage.toSize(context), style = style
            )
        }

and

@Composable
fun LinearDataUsage(
    networkStatus: Networks,
    networkUsage: DataUsageReport?,
    style: TextStyle,
    context: Context,
) {
...
        val usage = networkUsage?.dataByType?.get(activeNetwork.type.typeName)
        if (usage != null) {
            Text(
                text = usage.toSize(context), style = style
            )
        }

The composable correctly updates, while the curved content does until a screen change.
