Compose 1.6.0 full recomposition after keyboard appearing (iOS)

[piskunovvitaly]

Describe the bug When we click on any input to bring up the keyboard, we trigger a full recomposition several times starting with the ComposeUIViewController. This bug is specific to iOS and only occurs in Compose version 1.6.0. In previous versions (1.5.x) this problem do not exist.

Affected platforms

• iOS

Versions

• Kotlin version*: 1.9.22
• Compose Multiplatform version*: 1.6.0

To Reproduce Steps and/or the code snippet to reproduce the behavior:

1. Open any sample project with TextField
2. Click on TextField

Expected behavior Lack of full recomposition

A workaround if you don't rely on any other iOS animation in the meantime is to disable animations

@main
struct iOSApp: App {

    init() {
        FirebaseApp.configure()
        UIView.setAnimationsEnabled(false)
    }

    var body: some Scene {
        WindowGroup {
            ZStack {
                ContentView()
            }.preferredColorScheme(.dark).ignoresSafeArea(.keyboard)
        }
    }
}

This also causes unnecessary recompositions even after text field interaction. I describe my issue in a bigger detail in kotlin slack

UIView.setAnimationsEnabled(false) fixes it.
