After several hundred package updates over time this problem is no longer occurring, I suspect that it was something buggy in the XML library used by FotnConfig.

This is not noticeable if antialiasing is on, and most users default to antialiasing. * In ULTS 22 if there is a file '$XDG_CONFIG_HOME/fontconfig/fonts.conf' then some fonts are no longer found, or get rendered with rectangular shapes. I guess not many users customize their font settings. A telling example from ULTS 22: $ cat /etc/fonts/conf.d/10-antialias.conf <?xml version="1.0"?> <!DOCTYPE fontconfig SYSTEM "fonts.dtd"> <fontconfig> <!-- Use the Antialiasing --> <match target="pattern"> <edit name="antialias" mode="append"><bool>false</bool></edit> </match> </fontconfig> $ cp -p /etc/fonts/conf.d/10-antialias.conf $XDG_CONFIG_HOME/fontconfig/fonts.conf $ fc-list 'dejavu sans mono' family $ rm $XDG_CONFIG_HOME/fontconfig/fonts.conf $ fc-list 'dejavu sans mono' family DejaVu Sans Mono This happens also with a skeleton '$XDG_CONFIG_HOME/fontconfig/fonts.conf' (or '/etc/fonts/local.conf') too: $ cat > $XDG_CONFIG_HOME/fontconfig/fonts.conf <?xml version="1.0"?> <!DOCTYPE fontconfig SYSTEM "fonts.dtd"> <fontconfig> </fontconfig> $ fc-list 'dejavu sans mono' family $ rm $XDG_CONFIG_HOME/fontconfig/fonts.conf $ fc-list 'dejavu sans mono' family DejaVu Sans Mono None of these anomalies happen under ULST 20. My impression: symptoms vary and are weird, so probably it is something like a buffer overflow when reading the ".conf" files or the use of not-initialized memory.
