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.
It’s a bug that happens when you have multiple browser tabs opened at the same time, devs are fixing it, we just have to be patient and wait for the next release.
