void tst_QGuiApplication::windowIcon()
{
    int argc = 3;
    char *argv[] = { const_cast<char*>("tst_qguiapplication"), const_cast<char*>("-qwindowicon"), const_cast<char*>(":/icons/usericon.png") };
    QGuiApplication app(argc, argv);
    QIcon appIcon(":/icons/appicon.png");
    app.setWindowIcon(appIcon);

    QWindow window;
    window.show();

    QIcon userIcon(":/icons/usericon.png");
    // Comparing icons is hard. cacheKey() differs because the icon was independently loaded.
    // So we use availableSizes, after making sure that the app and user icons do have different sizes.
    QVERIFY(userIcon.availableSizes() != appIcon.availableSizes());
    QCOMPARE(window.icon().availableSizes(), userIcon.availableSizes());
