This issue also occurs on Mac OS 11.4 and Ubuntu 20.04.

When some fonts are not embedded in the pdf, we rescale (using some hard-coded scale factors) the glyph outlines from Liberation font in order to have a similar rendering as for the original missing font.
But we don't touch at all to the font hinting data and maybe when the font size is too small then the rendering is a bit incorrect.
