    Description

      On mac with a retina display the icons in the titlebar of a dockwidget are drawn without HiDPI. In the attached image the text is drawn in high resolution. In contrast the close and undock buttons are only rendered using the default resolution.

      The tested application uses qApp->setAttribute(Qt::AA_UseHighDpiPixmaps).
