REVISION SUMMARY
  Because of the nature of floating point math and various Qt and X11 bugs, limiting the
  scale factor increment to 0.0625 (6.25% in percentage form) will improve the display in
  many apps.
  
  For more information, see https://bugreports.qt.io/browse/QTBUG-66036 and the discussion
  in https://bugs.kde.org/show_bug.cgi?id=412447 and the following application bug reports:
