Text rendering problem with text scaling on Windows 11

    Description

      This seems to be a Windows 11 specific problem, at least not reproducible in Windows 10.

      When High DPI scaling is enabled ( i.e. QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling)) and system's display scale ((System > Display > Scale & layout > Scale) is set to 150% or 175%,
      some of the characters of the text are not drawn.

      The below is output in Application output.

      "QWindowsFontEngineDirectWrite::addGlyphsToPath: GetGlyphRunOutline failed (Parametro non corretto.)"
