Jetpack Compose version: 1.2.0-beta02
Jetpack Compose component used: LazyColumn/LazyList
Android Studio Build: Android Studio Chipmunk | 2021.2.1
Kotlin version: 1.6.21

Android 12 introduced a new overscroll effect. Lists are now stretching. Unfortunately, with Compose, this same effect can cause LazyLists to "block" the scrolling of the lists from time to time.

That issue can be bypassed this way:

CompositionLocalProvider(LocalOverScrollConfiguration provides null) {
    // Content here
}

Providing null to LocalOverScrollConfiguration causes the internal function rememberOverScrollController called from LazyList (on which LazyColumn depends) to return NoOpOverscrollController which essentially doesn't produce any overscroll.

You can find a video demonstrating the issue in a release build here.

Additionally, I created a simple Android Studio project which you can use to test the issue yourself. Everything required is contained within MainActivity. The MainActivity file also contains a Config object which you cause use to modify some aspects of the demo. It also includes a simple boolean DisableOverscroll which you can set to true to disable the overscroll effect as explained above.
