Bug 257087: x11-fonts/fontconfig problems with monospace font(s) after updating
from 2.13.93,1 to 2.13.93_1,1
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=257087



--- Description ---
No problem with a boot environment that preceded the update: 

    n247798-f39dd6a9784-b

I created, activated then booted a new environment: 

    n247798-f39dd6a9784-c

– ran `pkg upgrade`, rebooted, started Thunderbird, observed something wrong
with fonts, started Firefox, observed a recurrence of symptoms that are
associated with Mozilla bug 1695575. Maybe most significant: 

* normally (with my preferences) a monospace font is used for 
  the URL in the address bar

* after updating fontconfig from 2.13.93,1 to 2.13.93_1,1 
  a different font was used for the URL in the address bar and 
  (Mozilla bug 1695575) the user interface became 'too wide'. 


Temporary workaround – package locked
=====================================

I rebooted n247798-f39dd6a9784-b, locked fontconfig to 2.13.93,1. Created,
activated then booted a new environment: 

    n247798-f39dd6a9784-d

– ran `pkg upgrade`, rebooted. Fonts appear OK in Thunderbird and Firefox. 


Environment
===========

FreeBSD 14.0-CURRENT.
