Jetpack Compose version: I've tested on 1.3.0-alpha01 and 1.2.0-beta03

Jetpack Compose component(s) used: LazyColumn

Android Studio Build: 221.3427.89.2211.8689873

Kotlin version: 1.7.10

Steps to Reproduce or Code Sample to Reproduce:

Create a LazyColumn
Scroll
Memory 📈

Context:

We have a rather large (10k+ items) LazyColumn where scrolling (eventually) leads to the application grinding to a halt, constantly trying to free memory. It can't, we just keep getting lots of these:

Background concurrent copying GC freed 51964(1414KB) AllocSpace objects, 6(120KB) LOS objects, 0% free, 190MB/192MB, paused 101us total 1.483s

I took at heap dump at this point and basically all of the heap is used up by instances of SnapshotMutableStateImpl$StateStateRecord.

Replace LazyColumn with a RecyclerView (with each item being a ComposeView) and the memory leak is gone. App performance is night and day better.

I've been trying for hours to reproduce this in a trivial sample project and haven't had any luck yet. Raising this anyway just in case you have any ideas about what might be causing it. Obviously this makes LazyColumn completely unusable for us, so we'll stick to RecyclerView for now!
