Windows with freetype fontengine doesn't use available Bold/Italic font variants but auto generates them

Setting font engine to freetype

And using any font available on the system (i.e. Arial, Times New Roman... ) with style set to bold and/or italic style is generated instead of using available font.

I attached pictures from Font Sampler example with and without freetype.

Sometimes generated bold is wrong with bigger pixel size set to bigger than 63 gives output as shown in boldbug.png

void paintEvent(QPaintEvent * /*e*/)
{
    QPainter p(this);
    QFont font("Times New Roman");
    font.setBold(true);

    font.setPixelSize(63);
    p.setFont(font);
    p.drawText(10,70, "Times 63");

    font.setPixelSize(64);
    p.setFont(font);
    p.drawText(10,170, "Times 64");
}
