      I was pleasanty surpirsed to see Qt successfuly drawing GraphicsItems (both text and paths) under OS X HiDPI resolution modes. (tested using Quartz Debug)

      However two things break it if used:

      • QGLWidget as viewport
      • Item Cache

      Using any of these results in either all or selected items to be drawn pixelated.
