I have an issue that might be the same (even this one seems to be cryptic, feel free to move this elsewhere) :

when I use a listState that can be modified, e.g.

val listState = mutableStateOf(LazyListState())

@Composable
fun List() {
  LazyColumnScrollbar(
            state = listState.value,
            settings = ScrollbarSettings(alwaysShowScrollbar = true)
        ) {
            LazyColumn(
                state = listState.value,
            ) {
                 .....
            }
       }
}

then changing the listState (for a new one, with listState.value = LazyListState()) makes the scrollbar completely buggy
(unusable and showing randomly either position 0 or old liststate position).

without (alwaysShowScrollbar = true), the scrollbar just disappears completely

I think the issue is that LazyColumnScrollbar is not recomposed correctly, but LazyColumn is recomposed, so the states are desynchronized ? I could be wrong tho
