StackView element is shown again even if it's popped and hidden

[Mark81]

I'm surely missing something obvious.
I have this Item called viewWelcome.qml:

import QtQuick 2.0
import QtMultimedia

Item {
    id: root
    signal ended()

    Component.onCompleted: {
        mediaBackground.play();
    }

    Image {
        id: imgLogo
        anchors.centerIn: parent
        source: "qrc:/icons/Logo.png"
        rotation: -90
        width: parent.height * 0.7
        fillMode: Image.PreserveAspectFit
    }

    MediaPlayer {
        id: mediaBackground
        videoOutput: videoOutput
        source: "file:///mnt/resources/themes/default/demo.mp4"

        onMediaStatusChanged: {
            if (mediaStatus === MediaPlayer.EndOfMedia) {
                // all my tries to hide the elements
                root.visible = false
                root.opacity = 0.0
                mediaBackground.source = ""
                videoOutput.visible = false
                videoOutput.opacity = 0.0
                imgLogo.source = ""
                ended()
            }
        }
    }

    VideoOutput {
        id: videoOutput

        anchors.centerIn: parent
        anchors.horizontalCenterOffset: 700
        anchors.verticalCenterOffset: -200
        width: 1080 * 0.5
        height: 1920
        rotation: -90
        fillMode: VideoOutput.PreserveAspectFit
    }
}

Then in my main.qml:

import QtQuick
import QtQuick.Controls
import QtMultimedia
import Qt5Compat.GraphicalEffects

ApplicationWindow {
    id: window
    objectName: "window"
    width: 1920
    height: 1080
    visible: true
    visibility: "FullScreen"
    color: "black"

    Item {
        id: item
        anchors.fill: parent

        StackView {
            id: stack
            anchors.fill: parent
            initialItem: viewWelcome
        }

        PageWelcome {
            id: viewWelcome

            onEnded: {
                stack.pop()
                stack.push(viewContent)
                // try to hide it one more time...
                viewWelcome.visible = false
                viewWelcome.opacity = 0.0
            }
        }

        Content {
            id: viewContent
            // some stuff
        }
    }
}

So basically the behavior is the following:

1. on startup viewWelcome is the first item on the StackView
2. then the video ends, the item is popped and another one is pushed onto the stack

Great!
The problem is whenever I pop/push something else, or even when I quit the application, the initial item appears for a fraction of second. It's very annoying because I set all the available properties I know to hide that! And it's popped from the stack...

What can cause this behavior?

@Mark81 don't set an initial item, those can't be popped

[Mark81]

@J-Hilk are you sure? I can't find this information in the docs:

initialItem : var

This property holds the initial item that should be shown when the StackView is created. The initial item can be an Item, Component, or a url. Specifying an initial item is equivalent to:
Component.onCompleted: stackView.push(myInitialItem)

In fact, even pushing the first item manually:

Component.onCompleted: stackView.push(viewWelcome)

the behavior is the same.
Or are you suggesting the FIRST item cannot be popped? Hence I need to push a fake item with a black background?

[Mark81]

@Mark81 Tried but nothing has changed:

Component {
    id: fooItem

    Rectangle {
        color: "black";
    }
}

set as initialItem, then:

Component.onCompleted: stackView.push(viewWelcome)

but when the application quits, I see again for a while viewWelcome

@Mark81 said in StackView element is shown again even if it's popped and hidden:

yes, I had to do that, in one of my apps, or I would end up with multiple instances of a Bluetooth module, because one was never going destroyed even though I popped it, removing the initial item and using a push on construction fixed it for me. But it doesn't seem to fix it for you

can you give a minimal reproducible example for us to look at?
