Now that’s one interesting application. And a useful one too, because I now
found out the following:

   font-size 1-8: characters visible
  font-size 9-13: characters invisible
font-size 14-...: characters visible

If I disable font-smoothing completely in Xfce’s interface settings, the
characters are visible at any size. They are also visible at any size if I
choose xft or ft2 as backend for pango-view. Playing around with --hinting=none
does nothing; fonts are always hinted.

So it seems to be a Cairo-related issue … Either that, or something in my local
font configuration is definitely not right.


Regards, Mathias
