    I can not figure out what has changed in high DPI support in Qt 5.6.
    Application that I'm developing works good with Qt 5.5.1 without any additional steps. But with Qt 5.6 I have ugly pixelated fonts.
    What am I missing?

      Hi,

      What OS are you running ?

      AFAIK, parts of the changes are automatic handling but that's not all.

        @SGaist I have such results on MacBook Pro with Mac OS X 10.10.5, and display is 15,4-inch (2880 x 1800)
        Also I have to mention that I've tried to add following line:

        QApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
        

        But, unfortunately, it changes nothing.

          When are you setting that attribute ?
