Pamac marks AUR Packages under foreign, since i have only 2 AUR Packages self installed, i remove everything else which has a AUR Marker on it, but since i use pamac that gives a good overview, i never had interest’s in a Terminal command (if this even exists) to filter them.
But i recently removed on my PC/Laptop (both KDE) the AUR Foreign that you have too: breath2-wallpaper, spectre-meltdown-checker, libcroco,khtml, kjs, js78 that was recently one of this outdated and unsupported Repo Packages and that is in your List right now (outdated and should be orphan’s).
Create a System Snapshot just in case before you remove them.
I guess there could be some more, but i can’t help you with the other’s.
I control them with this:
Orphan paket check, Important for safety uninstallation:
(Required By : None)
(Optional For : None)
pacman -Qi "Package name"
Spoiler Alert:
I would change your Steam Topic: “Performance regression because of?”
and add Linux to it. Because Windows user’s complain’s all day long and has probably nothing to do with your error’s.
