Jetpack Compose version: 1.3.0-rc01

Jetpack Compose component(s) used: 1.7.20

Android Studio Build: #AI-222.3739.54.2221.9043926, built on September 9, 2022

Kotlin version: 1.7.20

Description: ImmutableList is considered stable by the compiler, but creating a list of integers using persistentListOf(0,1,2) will cause recompositions. Creating list using listOf(0,1).toImmutableList() won't.

Steps to Reproduce or Code Sample to Reproduce:

1. Add "org.jetbrains.kotlinx:kotlinx-collections-immutable:0.3.5" dependency
2. Paste code below:

@Composable
fun TestScreen() {
    var count by remember { mutableStateOf(0) }
    val listViaPersistentListBuilder = remember { persistentListOf(1, 2, 3) }
    val listViaCasting = remember { listOf(1, 2, 3).toImmutableList() }

    Column {
        Texts(listViaPersistentListBuilder) // will cause recompositions
        Texts(listViaPersistentListBuilder as ImmutableList<Int>)  // casting fixes the issue
        Texts(listViaCasting) // works as expected
        Button(modifier = Modifier.size(108.dp), onClick = { count++ }) { Text(text = "count++") }
        CounterText(count)
    }
}

@Composable
fun Texts(items: ImmutableList<Int>) {
    for (item in items) {
        Text(text = "Item $item ")
    }
}

@Composable
fun CounterText(count: Int) {
    Text(text = "Count: $count")
}
