    Description

      QRadioButton and QCheckBox look ugly when shown on a monitor where the device pixel ratio was rounded (either up or down) from a non-integer device pixel ratio.

       

      Reproduce by executing the attached code under Windows 10 using a screen with non-integer device pixel ratio. See also enlarged screenshots. The radio buttons look like poorly upscaled bitmaps.
