Error : qt_pixmapFromWinHBITMAP, failed create image of 1280x720

[tomer.vinay86]

I am working on multi threading : one thread is capturing the QImage of QWebView as QWebFrame :

void XXXXX::SaveImage(QWebFrame *frame)
{
    QImage image(frame->contentsSize(), QImage::Format_ARGB32_Premultiplied);
    image.fill(Qt::transparent);
    QPainter painter(&image);
    painter.setRenderHint(QPainter::Antialiasing, true);
    painter.setRenderHint(QPainter::TextAntialiasing, true);
    painter.setRenderHint(QPainter::SmoothPixmapTransform, true);
    frame->documentElement().render(&painter);
    painter.end();
 
    captureImage.push_back(image);
}

void XXXXX::SaveImage(QWebFrame *frame)
{
    QImage image(frame->contentsSize(), QImage::Format_ARGB32_Premultiplied);
    image.fill(Qt::transparent);
    QPainter painter(&image);
    painter.setRenderHint(QPainter::Antialiasing, true);
    painter.setRenderHint(QPainter::TextAntialiasing, true);
    painter.setRenderHint(QPainter::SmoothPixmapTransform, true);
    frame->documentElement().render(&painter);
    painter.end();

    captureImage.push_back(image);
}

To copy to clipboard, switch view to plain text mode 

and I use the other thread to popup the Qlist data.

But after 2-3 minutes, my application crashes with the below errors.

qt_pixmapFromWinHBITMAP, failed create image of 1280x720

QWaitCondition: Destroyed while threads are still waiting terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc LEAK: 6 RenderObject LEAK: 1 Page LEAK: 1 Frame LEAK: 2 CachedResource LEAK: 28 WebCoreNode
Anyone have an idea why this error is coming?
