Subject: bug#36320: 25.1; Do not prioritize Xresources over customized font, especially not *Font
Date: Thu, 20 Jun 2019 22:49:45 -0700

Hello friendly GNU Emacs folks!

If you set a default font using xrdb, it will override the default font
set using the Options menu (set default font, save options).

You can test it like so:

    $ echo '*font:variable' | xrdb -merge
    $ emacs
    
You'll notice that it overrides a default font saved in your .emacs
file. E.g., 

    (custom-set-faces
     '(default ((t (:family "Latin Modern Mono" :foundry "GNU" :slant normal :weight normal :height 120 :width normal)))))

This is very confusing behavior. It makes more sense that anything set
within a user's .emacs init file will override an Xresource preference —
which could have even been set by the site's system administrator, not
the user.

Please change the priority so that Xresources are ranked lower than a
user's emacs customizations for the default font.

By the way, although removing Xresource support altogether from Emacs
would solve the problem and is not a terrible idea, it would disappoint
people who like emacs to start up as quickly as possible. Setting the
default font in the .emacs file adds about 300ms to the start up time
compared to setting Emacs.Font in one's .Xresources file.

Thank you.
