Problem with fullscreen ApplicationWindow

jayhut

Hello,

I develop a Qt 5.5 application on Windows 7. The target device is a Windows 8.1 tablet.

The application works fine on Windows 7 but I have a problem with the ApplicationWindow (in fullscreen mode) on Windows 8.1.

When the window looses the focus (pressing the Windows button or the power button for instance), the application still runs in background but the window does not repaint itself.

Here is a snippet of my use of the ApplicationWindow:

import QtQuick 2.5
import QtQuick.Controls 1.4
import QtQuick.Window 2.2

ApplicationWindow{
    id: mainWindow
    title: qsTr("TestWindow")
    visibility: Window.FullScreen
    visible: true

    Rectangle {
        id: contentPanel
        anchors.fill: parent
        color: "#5d7071"

        Text{
            anchors.centerIn: parent
            horizontalAlignment: Text.AlignHCenter
            text: "Test Window\n(Click here to close)"
            font.pixelSize: 48
            color: "lightgrey"

            MouseArea{
                anchors.fill: parent
                onClicked: Qt.quit()
            }
        }
    }
}

Have you any idea to solve this issue?

Thanks.
