Updated to dev16 today and I cannot do this anymore. Why is mutableStateOf not allowing property delagates anymore? Am i missing something?

class Position(x: Int, y: Int) {
    var x by mutableStateOf(x)
    var y by mutableStateOf(y)
}

Maybe wrong import?

The import is androidx.compose.runtime.mutableStateOf

Nope, for getValue delegate: https://developer.android.com/reference/kotlin/androidx/compose/package-summary#(androidx.compose.State).getValue(kotlin.Any,%20kotlin.reflect.KProperty)

I found the same issue

Thank you @romainguy it works now with your suggestion

This isn't intended and might be a bug with kotlin 1.4.
