Keyboard flickering when programmatically hidden in Jetpack Compose

Question

When I programmatically hide the keyboard which is focused on the TextField, it flickering. How to get rid of this?

val keyboardController = LocalSoftwareKeyboardController.current
var text by rememberSaveable { mutableStateOf("") }
TextField(
    modifier = Modifier.fillMaxWidth(),
    value = text,
    keyboardOptions = KeyboardOptions(imeAction = ImeAction.Done),
    keyboardActions = KeyboardActions(
        onDone = {
            keyboardController?.hide() // Causes flickering
        }
    ),
    onValueChange = {
        text = it
    }
)

I also noticed that sometimes flicker occurs when you open the previous screen. Is it possible to see somewhere what exactly causes the keyboard to open and close?

I guess this is a Jetpack Compose bug on Xiaomi devices. I opened an issue in Google Issue Tracker: https://issuetracker.google.com/issues/296001700

I found that the bug persists even on a new clean project. I also accidentally discovered a similar bug in the ChatGPT app (created using Compose):

If I manually remove focus from EditText bug appears less frequently. When closing keyboard, it flickering approximately in 4 out of 10 cases.

val localFocusManager = LocalFocusManager.current
var text by rememberSaveable { mutableStateOf("") }
TextField(
    modifier = Modifier.fillMaxWidth(),
    value = text,
    keyboardOptions = KeyboardOptions(imeAction = ImeAction.Done),
    keyboardActions = KeyboardActions(
        onDone = {
            localFocusManager.clearFocus()
        }
    ),
    onValueChange = {
        text = it
    }
)

But it was not possible to completely get rid of him. I have already tried all possible solutions.

Feel free to comment in Google Issue Tracker if you have similar bug (you can test it using official ChatGPT app on Xiaomi device).
