Jetpack Compose, recompositing doesn't work when the compose layout is not in the foreground [Blur]

Recomposition breaks if a view is added to the layout container from above.
Situation: there is a profile screen, by tapping on the cell with the number, we load information in the back, whether the user can change the phone and, accordingly, turn the progress bar. If it cannot, we show an error (a custom view that is simply added to the very top of the container), after that the composition screen freezes and does not render changes, CircularProgressIndicator instead of hiding - just hangs. But it is worth clicking in any other place, the screen starts to be drawn correctly. In the photo below, the progress bar is stuck:
Code:
if (rightIconId != null && !isLoading) {
RightIcon()
} else if (isLoading) {
CircularProgressIndicator()
}
Calling validate() on the container does not fix the bug.
Update.
It turned out that the blur was breaking the rendering of the UI.

Prevent TopAppBar moving out of the screen when keyboard opens

Am I missing something, but why Scaffold's TopAppBar moves out of the screen when keyboard appears?
I have a simple layout:
setContent {
MyTheme {
Scaffold(topBar = { MyTopAppBar() }) {
ScaffoldContent(it)
}
}
}
Where ScaffoldContent is just a Column with a TextField.
When I press a TextField, keyboard opens and moves everything up . How can I make the bar stick at the top?
Tried:
android:windowSoftInputMode="adjustResize" or "adjustPan"
Instead of Scaffold use a Column and add elements there, but moves anyway
Expected:
TopAppBar to be at the top all the time, like in our Views system

With AdjustResize LazyColumn TextFields on the bottom won't open keyboard

Created a LazyColumn with textFields and it seems to have issue with "android:windowSoftInputMode="adjustResize"parameter.
When clicking a text field that needs to move up so it won't be hidden behind keyboard, causes issues when using AdjustResize parameter. The keyboard will open and then close again. It seems that textfield has lost a focus when ui is doing adjustResize.
Simple code example:
LazyColumn(state = rememberLazyListState()) {
for (i in 1..20) {
item {
TextField(value = "item{$i}", onValueChange = {})
}
}
}
And in AndroidManifest.xml I have
<activity
android:name=".MainActivity"
android:exported="true"
android:windowSoftInputMode="adjustResize"
...
Demo to show that keyboard is closed just after it opens. (This issue only happens when to click on item that needs adjustment to be visible when keyboard is open)
LazyColumn Textfield works correctly without AdjustResize focused item will be moved up and everything is fine. The reason why I would like to use AdjustResize is that in my actual app I have undo/redo buttons at the bottom of the screen and I would like to move them up when keyboard is opened, but it seems I need to use AdjustResize to make it work, but that brakes textFields.
So I was wondering how can I make LazyColumn TextFields to work with AdjustResize? (I'm using latest compose version: 1.3.1)

Why keybaord does not show after tapping back on Android 10?

I have an Android Jetpack Compose project where I show a screen with a InputField:
When coming to that screen, the keyboard opens automatically, ready to read the users entered characters.
The screen also includes a "imprint" link opening default webbrowser
On Android 11 and higher, when I tap the back button (Android hardware button, triangle) the already opened webbrowser disappears and the previous input screen show again and the keyboard again opens automatically.
On Android 10 (emulator and real device), when I tap the back button (Android hardware button, triangle) the already opened webbrowser disappears and the previous input screen show again but the keyboard is not shown on Android 10.
Whats the reason for missing keyboard on Android 10?

Try using
val focusRequester = remember { FocusRequester() }
modifier = Modifier
.focusRequester(focusRequester = focusRequester)
you can also use
LaunchedEffect(Unit) {
focusRequester.requestFocus()
}

Android keyboard is covering Qml TextField

I have a Dialog containing a header, footer, and content item which is a ListView:
Dialog {
width: 200
height: 200
x: 10
y: 100
header: Rectangle {
}
contentItem: ListView {
delegate: TextField {
// this is covered by the Android keyboard
}
}
footer: Rectangle {
}
}
On iOS the whole screen is shifted up so that the ListView's TextField (https://doc.qt.io/qt-5/qml-qtquick-controls2-textfield.html) owning the text cursor is always visible. On Android the TextField's cursor is covered by the Android keyboard. I already tried to set android:windowSoftInputMode="adjustResize" in the AndroidManifest.xml but without success.
Is there an easy way to make sure that the TextField currently owning the cursor is always visible? Or is the only solution to manually move the Dialog's y coordinate?

Regards,

The entire text view? No, that's not how keyboards work in Android. The only lever you have is the softInputMode, which is either pan or resize. In pan mode, the screen is scrolled up such that the cursor is always visible (but the rest of the text view may not be). In resize mode, the app is resized in the space above the keyboard, and then if needed shifted so the cursor is visible. This can sometimes make more of the screen visible, if you had empty space on screen and your layout is set to scale well (login screens frequently benefit). But there is no way to ensure the entire text view, or any other field, is still on screen. It's just not how Android works.
