I’ve seen it when the AJAX call to get the body parts times out or doesn’t work, but the raw HTML parts do load. That for me is most often when I’m on 3g wireless broadband connection, but I wouldn’t say i see it a lot. I then tend to hit Back, then Forward, and it re-displays and renders in full
This is an older post but I have what I think is a new rendering issue.
If there’s a forum post that has a very long paragraph of text, the word wrap doesn’t seem to work - it will cut a word in half if it neds to. I can only say I remember it happening for the past 3 or so days; no significant change on PC at my end. Were there any CSS tweaks recently that might explain this?
