Windows 10 Platform MenuBar hidden shortly before application is closed

XMLWordPrintable

      This makes the whole window "jump" when closing the application, instead of just smoothly fading out as it normally would.

      I would expect it to stay visible like other stuff in the application. See notepad-plus-plus-menubar-app-close.gif for the expected behaviour.

      Happens with Slate, and with this minimal example:

      import QtQml 2.2
import QtQuick.Controls 2.1

import Qt.labs.platform 1.0 as Platform

ApplicationWindow {
    id: window
    objectName: "window"
    width: 1200
    height: 800
    visible: true

    onClosing: {
        close.accepted = false
        Qt.quit()
    }

    Platform.MenuBar {
        Platform.Menu {
            id: fileMenu
            objectName: "fileMenu"
            title: qsTr("File")

            Platform.MenuItem {
                objectName: "newMenuItem"
                text: qsTr("New")
            }
        }
    }
}

      If I take away the onClosing handler, the problem goes away.
