Description of problem:
changing the WM_CLASS of a window doesn't have an effect of updating the icon selected from the matching .desktop file
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. dnf install libreoffice to install the desktop files and icons etc
2. g++ demo.cxx `pkg-config --cflags --libs gtk+-3.0` -lX11
Name of window in top panel changes from "LibreOffice" to "LibreOffice Writer", but the icon shown in the bottom panel remains as the original "startcenter" icon and doesn't change to the "writer" icon
This is the scenario for LibreOffice which attempts to bundle e.g. "writer" windows together. (https://bugzilla.gnome.org/show_bug.cgi?id=632229 and https://wiki.gnome.org/Projects/GnomeShell/ApplicationBased) But where when there is one window open and its contents closed, the window reverts to a "startcenter" type.

what would ideally happen
Its unclear to me if under wayland there is even the theoretical possibility to continue to support one running process impostering as multiple applications.
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 23 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
