I don't think that the fact the package is marked a X.org is relevant, it's the default theme package installed with a fresh Ubuntu installed.
As said before, the package reinstall fixed the problem, so I could not reproduce it. My shell history show no modification of the theme path (except for a copy to a custom one). But here's some ps ou journalct that I copied at that time Here's a copy of ps (first column is cpu) ❯ ps -eo pcpu,pid,user,args | sort -k 1 -r | head - 99.8 6777 olivier+ /usr/libexec/gsd-keyboard 99.8 6370 olivier+ /usr/bin/update-notifier 99.7 6779 olivier+ /usr/libexec/gsd-power 99.7 6367 olivier+ /usr/lib/update-notifier/ubuntu-advantage-notification 99.7 5487 olivier+ /opt/sublime_text/sublime_text --detached <= manually launch (click) 99.7 5382 olivier+ /usr/bin/nextcloud --background 99.6 6780 olivier+ /usr/libexec/gsd-wacom 99.6 6771 olivier+ /usr/libexec/gsd-color 99.6 6446 olivier+ /usr/libexec/xdg-desktop-portal-gtk 98.7 5034 olivier+ /usr/libexec/evolution-data-server/evolution-alarm-notify Most of the process are systemd sub-processes.
