Sorry if this has already been posted but a quick glance and i didnt see it. For the gif I was scrolling through fast to see it occur but it has happened enough with organic usage I felt I needed to post. I checked two post from the video and its not reposted content. Upvoting one upvoted both, both have identical comments.
This is actually an issue with the Lemmy API that I noticed while working on my own Lemmy app. Basically pages are fetched from the api in order eg 1.2.3.4… and each of those pages can have up to 50 posts, I believe. Now say you fetch page 1, then browse for a bit before reaching page 2. Now during that time new posts were submitted, and now some of the page 1 content was pushed down to page 2. When page 2 is fetched it now contains a duplicate post from page 1 because the server doesn’t know the order or starting index from when you fetched page 1.
I think the api needs to add support for timestamps that it can be submitted with api requests so that fetching content is based on the time that page 1 was fetched.
As for this issue, if the developer is seeing this. I resolved this in my app by filtering out duplicate post ids when fetching new pages. It’s not ideal, but it’s all I could think of to do.
Yeah I think this is exactly right and I think I’ll have to do what you did. Looking forward to checking out Lemming.
I’m not sure if this is the same issue, but often, as I’m scrolling through comments on a post, the comments will start over and repeat from the beginning. It’ll continue as long as I keep scrolling, too. I never can make it to the end of the comments, as the list just keeps repeating over and over.
