Mac does not render text correctly when painter scaled.

 
#include <QtGui>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QGraphicsScene scene;
    QGraphicsView  view(&scene);

    QFont font;
    font.setFamily("Arial,sans-serif");
    font.setPointSize(11);

    QGraphicsTextItem *item = scene.addText("Test Set poSi D Hh", font);
    view.scale(6.0,6.0);
    view.setWindowTitle("Graphics Item - good");
    view.show();


    QTextDocument	docu2;
    docu2.setDefaultFont(font);
    docu2.setPlainText("\n\n\nTest Set poSi D Hh");

    QImage	 img2(QSize(1024, 1024), QImage::Format_ARGB32);
    QPainter	 imgPainter2(&img2);

    QTransform trans ;
    trans.scale(6.0,6.0);
    imgPainter2.setWorldTransform(trans);

    docu2.drawContents(&imgPainter2);

    imgPainter2.end();
    QLabel label2;
    label2.setPixmap(QPixmap::fromImage(img2));
    label2.setWindowTitle("Scaled image - not so good");

    label2.show();

    return app.exec();
}
