, that is a lot of memory usage, do you have a lot of tabs open in a web browser, then it is ok. For the rest, log shows no issue, no journal errors, no conflicting packages not from the KaOS repo (though it would be good to clean the system once a year or so from packages removed from the KaOS repo, kaptan for example has been gone 2 years, see the pacman -Q output in the log).
But, is there still an issue for this with your user?
mrcrowley it works well with old user
