When the window is maximized, the taskbar is frequently clicked (to switch the window between maximized and hidden directly), and the memory keeps growing

In the case of QApplication::setAttribute(Qt::AA_UseOpenGLES), put a custom title bar maximize button and QWebengineview in the client area, click the maximize button of the custom title bar to maximize the window, and then frequently click the task bar icon, the window switches back and forth between maximized and hidden, and the memory keeps growing. (If you click the maximize button of the system's own title bar, the memory is normal)
