I have just updated to 19.10. Now XFCE windows panel shows small number in black circle over window icon in the panel that amounts to the number of grouped windows. It is mighty annoying and it looks ugly.
Is there a setting that I can change to remove that number?
UPDATE: I have filled a bug report here: https://bugs.launchpad.net/ubuntu/+source/xfce4-panel/+bug/1850984
