Hello Max, that option has been introduced with Qt 5.6 and we’re still using Qt 5.4. We tried switching to Qt 5.6 when it came out but encountered some glitches on Windows due to Qt itself, so we decided to skip the adoption of 5.6. We could add this option with the next version if we update Qt. Thank you for the suggestion!

Just add before first line of code: QGuiApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
