My app in Qt 5.7, Windows 7, 64 bit-compile crashed in d3d11sdklayers.dll

TonyN

I create an app on Windows 7, compiled as 32 bit, and it runs fine. However when I switch everything to 64 bit, the app could not run. It crash in d3d11sdklayers.dll. Here is the stack trace:

In EMnetXClient it crashes right at
QQmlContext*rootContext = engine.rootContext();

Any clue?

Hi,
Could you provide a little bit of your code surrounding line 169 in main()?

Kind regards.

QQmlApplicationEngine engine;
    QtWebEngine::initialize();
    QQmlContext*rootContext = engine.rootContext(); // <<< Crash here

    rootContext->setContextProperty("deviceID", QVariant::fromValue(g_config.queueName()));
    rootContext->setContextProperty("webSiteURL", QVariant::fromValue(g_config.websiteUrl()));
    rootContext->setContextObject(p_gCommStatus);

    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

    initTrayIcon(engine);

    return app.exec();

The initTrayIcon function:

void initTrayIcon(QQmlApplicationEngine &engine)
{
    QObject *root = 0;
    if (engine.rootObjects().size() > 0)
    {
        root = engine.rootObjects().at(0);

        QAction *minimizeAction = new QAction(QObject::tr("Mi&nimize"), root);
        root->connect(minimizeAction, SIGNAL(triggered()), root, SLOT(hide()));
        QAction *maximizeAction = new QAction(QObject::tr("Ma&ximize"), root);
        root->connect(maximizeAction, SIGNAL(triggered()), root, SLOT(showMaximized()));
        QAction *restoreAction = new QAction(QObject::tr("&Restore"), root);
        root->connect(restoreAction, SIGNAL(triggered()), root, SLOT(showNormal()));
        QAction *quitAction = new QAction(QObject::tr("&Quit"), root);
        root->connect(quitAction, SIGNAL(triggered()), qApp, SLOT(quit()));

        QMenu *trayIconMenu = new QMenu();
        trayIconMenu->addAction(minimizeAction);
        trayIconMenu->addAction(maximizeAction);
        trayIconMenu->addAction(restoreAction);
        trayIconMenu->addSeparator();
        trayIconMenu->addAction(quitAction);

        QSystemTrayIcon *trayIcon = new QSystemTrayIcon(root);
        trayIcon->setContextMenu(trayIconMenu);

        trayIcon->setIcon(QIcon(":/Images/heart.svg"));
        trayIcon->show();
    }
}

Hi, if you compile in Release mode does it still crash the same way?

TonyN

@kshegunov I check the the debug log in the 32 bit version, and I think there is something relate to it. The line 168 " QtWebEngine::initialize();" is actually show a warning
D3D11: ERROR: ID3D11Device::CheckFormatSupport: Format (null) is not available at the current FeatureLevel. [ MISCELLANEOUS ERROR #2097402: CHECKFORMATSUPPORT_FORMAT_NOT_SUPPORTED ]

This is actually the culprit that crash the app in 64 bit version. I step thru the code in 64bit, and at that location, I got an access violation. The next line (169) will stop the app.

@hskoglund Interesting... the release version of 64bit does not!
How so!!?

@TonyN
From what I can tell from your code you aren't doing anything wrong. Obviously there's some problem with initializing direct 3D, but what exactly causes this I don't know, sorry.

Kind regards.

@TonyN

Hi, TonyN
Have you solved it? I have the same problem.

TonyN

@zhong-san No, I submitted a bug report and was accepted, but it still not resolve yet

TonyN

I end up used a different graphic board. The driver for Intel HD 3000 just buggy and they end support on 2015!. I don't know how to get around this with old computer from customers yet
