    • Windows 10.
      Notebook + 2 external monitors.
      Main display: 32inch 4K, 150% display scaling.

      When using QDS in high DPI mode with 150% display scaling on Windows, the QDS application display scaling is incorrect, including the design editing area.
      It appears as if 200% scaling is being used, rather than 150%.

      A workaround is to set QT_SCALE_FACTOR_ROUNDING_POLICY=PassThrough in a console before launching QDS, but there seems to be no Preferences setting for this?
