Subject: 30.1.90; Leuven theme causing strange frame issues?
Date: Tue, 15 Jul 2025 23:03:44 -0400

Hello,

I'm experiencing a bit of weird bug, but have successfuly reproduced it
with a clean minimal setup and fixed it by commenting out one line from
the Leuven theme.

This line is causing the problem:

   ;`(lui-highlight-face ((,class (:box '(:line-width 1 :color "#CC0000") :foreground "#CC0000" :background "#FFFF88")))) ; my nickname

The issue occurs in the following situation:

I regularly bring up a new frame with `emacsclient -c -n`. I've just
started to use emacs Slack integration, and when I launch
`(slack-start)`, I get the following message

face-spec-set-2: Invalid face box: quote, (:line-width 1 :color
"#CC0000")

And from then onward, when I try to bring up a new frame, I cannot. The
*scratch* buffer opens in an existing frame.

This is reproducible with a small init.el that only contains:

; set up use-package
(load-theme 'leuven)
(server-start)
(use-package slack
   ; Generic Slack conifg here
   )

When I comment out the `lui-highlight-face` above, the bug goes away.

This is a quoting problem.  This should instead say

    `(lui-highlight-face ((,class (:box (:line-width 1 :color "#CC0000") :foreground "#CC0000" :background "#FFFF88")))) ; my nickname

Yes, that fixes it. Dark theme has the same issue. Patch attached.
