Just pushed a fix, please test.

When I was adding the Flex mechanism, I referred to the Type 1 spec, which only mentions using `rmoveto' commands to provide the points. Thus I had not added the proper check to `vmoveto' and `hmoveto'.

Hopefully this simple fix solves the issue completely, I think it does..

Confirmed.  Note that the font in question is a Type1 font, not a TTF.

Reassigning.  Ewald, I'm sending you the font, please hava a look!

Please send the font privately to me.  I cannot uncompress the PDF file to extract it since I don't have the owner password.

Regression can be seen on provided screenshots.

  1. screenshot-1.png - `ftview` running with freetype-2.8 (all is OK)
  2. screenshot-2.png - `ftview` running with freetype-2.9 (rendering artifacts)


Font `Octavian MT Regular` can be extracted from this PDF file: https://tug.org/texshowcase/partofTheBookofTea.pdf, or I can attach it to this bugreport if you need it.
