Xubuntu 22.04/xfce.
I noticed a very long entry in the xfce4 panel configuration file xfce4-panel.xml
(~/.config/xfce4/xfconf/xfce-perchannel-xml/
), for plugin "pulseaudio":
<property name="plugin-10" type="string" value="pulseaudio">
<property name="enable-keyboard-shortcuts" type="bool" value="true"/>
<property name="enable-mpris" type="bool" value="true"/>
<property name="mixer-command" type="string" value="pavucontrol"/>
<property name="mpris-players" type="string" value="brave.instance179309;chromium.instance10173;chromium.instance10510;chromium.instance10607;chromium.instance10818;chromium.instance10881; ... chromium.instance9879;firefox.instance10260;firefox.instance10801 ... firefox.instance9880;parole;vlc.instance3789"/>
"Chromium.instanceXXX" repeats 328 times and "firefox.instanceXXX" repeats 135 times.
It seems that this only applies to entries for firefox and chromium browsers.
In catalog xubuntu-default-settings: /etc/xdg/xdg-xubuntu/xfce4/xfconf/xfce-perchannel-xml/
there is no file xfce4-panel.xml
.
Where to look for the source file and what could be causing this problem?
Regards
P.S.
I forgot to add:
Deleting the entry with xfce4-settings-editor
does not solve the problem.
After a few days, the value increases again.
