Wrong fullscreen size in Android

[Gustavo Serra]

Hi!

I am having an issue when trying to set immersive mode for my Android app. The screen content is shifted due to the notch area in my cellphone. I am not interested in using the cutout edges in this particular app. The code works fine on devices with no notch.
Here is the sample code to reproduce the problem:

import QtQuick

Window {
    visibility: Window.FullScreen
    // If I use the lines below, the code works, but why?
    // y: Screen.desktopAvailableHeight - height
    // x: Screen.desktopAvailableWidth - width

    Rectangle {
        width: 30
        height: parent.height
        color: "red"
        anchors.right: parent.right
    }
    Rectangle {
        width: parent.width
        height: 30
        color: "blue"
        anchors.bottom: parent.bottom
    }
}

Here are the results:

The rectangles don't appear. Is this a bug with Qt or is something wrong with the code? I tested using Qt 6.6.3 and 6.8.1.

If I use the commented lines, the area is set properly, but this seems like a workaround. Honestly, I don't understand why it should work as I am not changing the size, only the coordinates.

I appreciate any help you can provide.
