I just installed the 0.18.0 release candidate 1 of the lemmy-ui component.
This version removes websockets and should solve many strange issues. Like the glitching vote totals, sudden changes of posts etc.
Let me know if you see improvements, or new issues.
I’ve had this happen sometimes. I’ll open a post and comment on it, only to find that I’m commenting on a different post. I don’t know why that happens. May be the post scrolls the moment you’re clicking the link and you get the one before that.
