    I am following the example from [https://doc-snapshots.qt.io/qt5-5.9/activeqt-activeqt-webbrowser-example.html](link url). Building against QT 5.13.2. But it always hit this assert and crash.

    Q_ASSERT(window == topLevelWindow || topLevelWindow->isAncestorOf(window, QWindow::ExcludeTransients));

    Qt5Guid.dll!QBackingStore::flush(const QRegion & region, QWindow * window, const QPoint & offset) Line 252 C++
    Qt5Widgetsd.dll!QWidgetBackingStore::qt_flush(QWidget * widget, const QRegion & region, QBackingStore * backingStore, QWidget * tlw, QPlatformTextureList * widgetTextures, QWidgetBackingStore * widgetBackingStore) Line 165 C++
    Qt5Widgetsd.dll!QWidgetBackingStore::flush(QWidget * widget) Line 1413 C++
    Qt5Widgetsd.dll!QWidgetBackingStore::doSync() Line 1294 C++
    Qt5Widgetsd.dll!QWidgetBackingStore::sync() Line 1150 C++
    Qt5Widgetsd.dll!QWidgetPrivate::syncBackingStore() Line 1968 C++

      Hi
      It seems the example was later removed so could be its not working anymore.
      Does it work on same windows verson using Qt5.9 ?
