    Description

      Opening menus in a QML app leaks memory when QQuickWindow::setSceneGraphBackend is set to QSGRendererInterface::Software.

      Steps to reproduce:

      • run the sample attached.
      • go back and forth between the app menus and keep opening them.
      • monitor the memory consumpion, for example via 'Task Manager' on Windows.
        EXPECTED: the memory consumpion is stable.
        ACTUAL: the amount of allocated memory keeps rising steadily with each opening of a menu.

      For comparison, test without the line 'QQuickWindow::setSceneGraphBackend(QSGRendererInterface::Software);'
