Possibly? Maybe what is happening is that I will be 10+ deep posts in a thread, then I leave the topic, and when I open the topic again I’m brought to the first post of the last thread I was reading?
If I’m following you correctly anyways. It’s a bit jarring. Maybe I mentally expect this to work like Reddit where the OP at the top is always opened, instead of my reading position being resumed.
I’m pretty sure it wasn’t returning to exactly where I was though. I’ll pay more attention and see if this is what’s indeed happening.
Another similar thing I am experiencing (which may be related) is frequently I will scroll up or down and it jumps back to the same post, like it’s stuck on it. I often have to refresh, or leave and come back.
I’m not sure when/why this happens, I’ll try to reproduce it more consistently.
This is not the only bug I’ve seen, but as far as the “lag” some people reported, I noticed this is mainly people using Tor Browser, or Vanadium on GrapheneOS, both of which will disable JavaScript JIT compilation.
Lockdown Mode on iOS also disables JIT, I wonder if it will be similarly affected. I’ll mess around with it a bit.
Worse performance is definitely expected with JIT disabled, but if it is only happening in these threads and not regular ones, I wonder if you are using some more intensive JavaScript feature that could be optimized. I’ve only ever noticed lag with complex cryptographic computation when JIT is disabled, never a noticeable performance impact on something basic like a forum.
I don’t have a great suggestion either honestly, but it is very annoying to see a topic show up at the top of “Latest” and have no way to see what the latest post actually is. I’ve resorted to clicking the profile of the latest commenter on the homepage and then finding their latest post lol (and I saw another user independently post about using this workaround as well)
