The unexpected Scroll-Of-New-Content when browsing seems to be happening when a newly loaded community from another instance gets loaded onto the server. I’m not sure if this is a local instance setting or a global Lemmy issue.
Please move or delete if it’s not appropriate for bringing up on the local instance, or it’s been covered and I missed it. I’m still getting used to how Lemmy federation operates and I’m not familiar with the instance-side options.
I’ve noticed that too. Every time I’m browsing all-c/new to find new communities and information, I’ll see posts from 2 years ago and (feels like) all the posts between then and now. Glad it’s being worked on.
