How to disable automated screen lock after a system update?

After my most recent pamac update my system now has a screen timeout/lock enabled which I didn't have set up before. This seems to stem from light-locker having a _lock after screensaver 5_ setting showing via light-locker --debug, but I don't know what settings the update actually modified since the power manager still claims the screen should never sleep. So how can I figure out what has been modified without my consent and fix this again?
