I was wondering if someone might be able to help me understand why I am getting a leak. As far as I can see, it is caused by my Material3 DropDownMenu. More in thread...

And this is my DropDownMenu code:

var showMenu by remember { mutableStateOf(false) }

                   DropdownMenu(
                        expanded = showMenu,
                        onDismissRequest = { showMenu = false }
                    ) {
                        DropdownMenuItem(text = { Text(text = "Stats") }, leadingIcon = {
                            Icon(
                                imageVector = Icons.Filled.Score,
                                contentDescription = "Score Icon"
                            )
                        }, onClick = {
                            navigator.navigate(StatsPageDestination)
                        })
                        DropdownMenuItem(text = { Text(text = "Themes") }, leadingIcon = {
                            Icon(
                                imageVector = Icons.Filled.Palette,
                                contentDescription = "Palette Icon"
                            )
                        }, onClick = {
                            navigator.navigate(ThemingPageDestination)
                        })
                        DropdownMenuItem(text = { Text(text = "History") }, leadingIcon = {

                                contentDescription = "History Icon"
                            )
                        }, onClick = {
                            navigator.navigate(HistoryPageDestination)
                        })
                    }

It looks like that might be the same issue as https://issuetracker.google.com/issues/206177594

[Nat Strangerweather]

Ah yes, it looks like it. What's the situation regarding a fix?

[Alex Vanyo]

It’s being tracked, but no estimate on when it’ll be fixed
