REVISION SUMMARY
  During Pre-Plasma5 the hard-coded height of 20 of the progressbar was
  changed to instead be taken from the theme via the "hint-bar-size":
  commit cee9c928e3855b68daf14760ed71aa961f231172 <https://phabricator.kde.org/R242:cee9c928e3855b68daf14760ed71aa961f231172>
  
  As fallback for old themes in absence of the hint the default height
  since some time later has been derived from the sum of the heights of
  the elements "bar-inactive-top" & "bar-inactive-bottom".
  
  Which though for the Air and Oxygen themes results in the small heights
  of respective 10 & 4. As a result the visual appearance of the theme
  differs from what people remember of the time when the themes were
  designed.
  Ideally the theme designer would tune the actual value to something they
  prefer. Until then setting the hint to restore the visual appearance over
  the currently pretty slim or even too slim one should improve things
  already.
