Does this manifest on that other platform that now offers extra high resolution displays (a.k.a. "Retina") i.e. MacOS?
If we go for the solution involving: "QGuiApplication::setAttribute(Qt::AA_EnableHighDpiScaling);" we will need to wrap it in "#if QT_VERSION >= 0x050600"..."#endif" so it doesn't throw a complier error on older versions (e.g. the 5.0.2 that is used by the Travis C.I. system for Linux testing)...
