bug focus when display error message in latex mode

[TimotheeMathieu]

Reproducing

Try to compile (C-c C-c) in Auctex mode, the following latex doc for instance:

\documentclass{article}
\begin{document}
\thiscommanddoesnotexist
\end{document}

This will give an error. When I look at the error with C-`, the error buffer is displayed in another frame, the focus shift to the error frame and directly shift back to the initial window which is a bit annoying. I would have preferred the focus to stay on the error window.

Other useful info

• Emacs version: 28.1
• frames-only-mode version: 1.0.0
• Operating system (and version): Archlinux
• Window manager (and version): i3 v 4.20.1

So this is partly up to your emacs config (configurable with display-buffer-alist) and partly up to your window manager.

You could try this:

(add-to-list 'display-buffer-alist
             '("\\*tex-shell\\*"
               ;; function to display this kind of buffer
               (display-buffer-pop-up-frame)
               ;; action alist
               (inhibit-switch-frame . t)
               ))

But, as noted in the emacs docs for inhibit-switch-frame, if your window manager always focuses the latest frame then you'd need to change that too.
