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.
FYI, I needed to drop all cached files from
lemmy.worldin chrome afterwards. Otherwise clicking on the top right profile button would shift the entire page down.
