LazyColumn TextStyle 上的 Jetpack Compose 错误无法转换为 androidx.compose.runtime.RecomposeScopeImpl

Question

我正在使用此处找到的一些示例代码探索 Jetpack Compose，但是它在上下滚动时一直崩溃。有时它根本不会崩溃，但如果您快速滚动，它似乎发生得更多。

我目前正在使用 compose 版本 1.0.0-rc01，但也尝试过 compose 1.0.0-Beta09，结果相同。希望对发生的事情有任何见解。虽然我很欣赏它的早期，但我确实认为 compose 看起来很有希望。提前致谢。

这是错误：

代码如下：

        super.onCreate(savedInstanceState)
        setContent {

                Surface(color = MaterialTheme.colors.primaryVariant) {
                    Greeting("Android")
                }
            }
        }
    }
}

@Composable
fun Greeting(name: String) {

    Row() {
        Column(modifier = Modifier.padding(16.dp)) {
            Text(
                text = "Hello $name!",
                modifier = Modifier.padding(bottom = 8.dp).fillMaxWidth(),
                style = MaterialTheme.typography.h5
            )
            LazyColumnDemo()
        }
    }
}

@Composable
fun LazyColumnDemo() {
    val list = listOf(
        "A", "B", "C", "D"
    ) + ((0..100).map { it.toString() })
    LazyColumn(modifier = Modifier.fillMaxHeight()) {
        items(items = list, itemContent = { item ->
            when (item) {
                "A" -> {
                    Text(text = item, style = TextStyle(fontSize = 80.sp))
                }

                    Button(onClick = {

                }
                "D" -> {
                    Text(text = item)
                }
                else -> {
                    Text(text = item, style = TextStyle(fontSize = 80.sp))
                }
            }
