I can confirm that this is still an issue on trunk.
My Emacs welcome screen says:
GNU Emacs 29.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.29,
cairo version 1.16.0) of 2022-06-11
Invoked as:
emacsclient -F '((name . "foobar") (title . "foobar-title"))' --create-frame -a ""
xprop reports:
WM_CLASS(STRING) = "emacs", "Emacs"
WM_ICON_NAME(STRING) = "foobar"
_NET_WM_ICON_NAME(UTF8_STRING) = "foobar-title"
WM_NAME(STRING) = "foobar-title"
_NET_WM_NAME(UTF8_STRING) = "foobar-title"
This affects me in that I run simultaneous emacs instances as two different users and have different icons configured for the different users. Now that I can't change WM_CLASS, both emacs instances appear under the same icon under my desktop manager, which is very frustrating.
Cheers,
Colin
