Perhaps I'm missing something, but why not skip the processEvents call
altogether and just queue an event to do the resizing later?
E.g:

void MyApp::show()
{
    QSettings settings;
    QSize sz = settings.value("MainWindowWSize",QSize(1200,700)).toSize();
    QPoint pos = settings.value("MainWindowPos",QPoint(180,190)).toPoint();

    if (sz.width() > 0 && sz.height() > 0)  {
        resize(sz);
        move(pos);
    }

    BaseClass::show();

    // The lambda is just quickest to write, you can use a private slot as
well.
    QTimer::singleShot(0, [sz, pos] () -> void  {
        if (sz.width() > 0 && sz.height() > 0)  {
            resize(sz);
            move(pos);
        }

        raise();
    });
}
