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 get “SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data”
Clearing the browser cache resolved the issue.
