When I use the following code, the Text inside Scaffold is white (I can barely see it) in the debugging device (Xiaomi Pocophone F1). The weird thing is when I rotate the phone the text becomes black like it shoud be. The button I have added calls another activity which is a default and simple hello world. If I press the button and go the the second activity and then go back, the text is fine. The third time that I go back and forth, the text breaks again and there is nothing to make it black again.

                    This is an example of a scaffold. It uses the Scaffold composable's parameters to create a screen with a simple top app bar, bottom app bar, and floating action button.

                    It also contains some basic inner content, such as this text.
                """.trimIndent()
                )
                OutlinedButton(

                    modifier = Modifier.padding(8.dp)
                ) {
                    Text("Add Shop")
                }

            }
        }
    }

    @Preview(showBackground = true)
    @Composable
    fun DefaultPreview() {
        MainUI()
    }
}

I have a thought that it may be the use of ExperimentalMaterial3Api but I cannot be sure.
The device’s API is 29 (Android 10.0).

Thank you in advance.
