Qt6: FullScreen on Android

[bunjee207]

Greetings Qt coders,

Starting with Qt6, there seems to be an issue with fullscreen on the Android platform.

With 6.2.1. The navigation bar area at the bottom stays white. This was not the case using Qt 5.15.2. It seems it could be arranged with native wizardry but I'd much rather have the appropriate behavior by default.

Anyone had that issue before ?

To reproduce I've added the following to the Qt gallery sample:

MouseArea
    {
        property bool fullScreen: false

        anchors.fill: parent

        z: 1000

        onClicked:
        {
            fullScreen = !(fullScreen);

            if (fullScreen)
                window.showFullScreen();
            else
                window.showNormal();
        }

        Rectangle
        {
            anchors.fill: parent

            opacity: 0.5

            color: "blue"
        }
    }

Could be a regression from this: https://forum.qt.io/topic/44970/problem-with-fullscreen-mode-in-android-with-qt-5-3-1
