    Description

      Maximizing a frameless window using shortcut (Winkey+ArrowUp) makes the window fullscreen
      Expecting result: windows taskbar is visible

      Code:

      #include <QApplication>
#include <QWidget>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QWidget w(0, Qt::Window | Qt::WindowMinMaxButtonsHint | Qt::FramelessWindowHint );
    w.showNormal();
    return app.exec();
}

      After building, use Winkey+ArrowUp to maximize the window, and see the result.

      Some other information:
