I noticed CPU utilization was up 25% constantly and the syslog was filled with errors from caja plugins. I did a timeshift restore to 11/30 and then did updates one by one. The culprit is xdg-desktop-portal. I removed it from my system and the problems stopped. Apparently this package serves no purpose on a system that does not used snapd or flatpak anyway.
