Subject: 25.3; window title for multiple frames
Date: Sun, 20 Jun 2021 17:32:57 +0200

This is a "old bug": When you start Emacs with a single frame, the
"window" title is "Emacs <at> host.domain.org", independent on the buffer you
are visiting in single-window mode.
However when you open another frame (C-x 5 b), the tiles of the
"windows" change to the buffer name (precisely: to the name of the
active window when there are multiple windows in the frame).
I think it would be both, consistent and helpful if Emacs would use
"window" title "Emacs <at> host.domain.org X" in all cases, where X could be
either the name of the active window in the frame, or a (possibly
abbreviated) list of windows being displayed in that frame.
Note: I'm using "window" in double-quotes when I talk about the window
manager's windows (like X11 windows), not about Emacs windows (that are
parts of a frame).

It would be more consistent -- but I think the idea here is that if you
just have one frame, then it's useful for that frame to be named
something with "emacs" in the name.  If you have several frames, then
that's not useful any more, so it switches to using buffer names as the
frame title instead.

So this is working as intended, so I'm closing this bug report.

As Andreas said, `frame-title-format' can be used to customise this to
your liking.
