Multi instance trigger "Check failed: !IsCefShutdown()"

[hcaihao]

Sample code:

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
{
    ui.setupUi(this);

    m_pCefWidget1 = new QCefWidget("https://www.baidu.com");
    m_pCefWidget2 = new QCefWidget("https://www.baidu.com");
    m_pCefWidget1->setAutoDestoryCefWhenCloseEvent(true);
    m_pCefWidget2->setAutoDestoryCefWhenCloseEvent(true);
}

MainWindow::~MainWindow()
{
    delete m_pCefWidget1;
    delete m_pCefWidget2;
}

The app crashing when closing window, how to delete qcefwidget correctly.

[0812/134958.089:FATAL:shutdown_checker.cc(52)] Check failed: !IsCefShutdown(). Object reference incorrectly held at CefShutdown
glacier.exe has triggered a breakpoint.
