on this page looking myself it seems to be a missing favicon-* class

likely the same css issue as The favicons on stackexchange.com/users/ seem to be stacked on top of one another

enter image description here

  • I can confirm this. @IlmariKaronen Anna said it's fixed on dev but for some reason the fix isn't working (yet) on production.

  • Ah, yes, I can repro this now. I was looking in the wrong place, sorry. Here's a link to a page where you can see this; look in the sidebar. Mar 21, 2014 at 12:39
  • Actually, this is a duplicate; Anna states in the comments she'd look into the issue today (and she's in US, so 'today' starts later for her). Mar 21, 2014 at 12:44

This seems to have been caused by the deployment of the new top bar to http://stackexchange.com. The problem is that both the topbar style sheet and the stackexchange.com style sheet are using the favicon class to display site icons, but they're using it in completely different ways. (The top bar is using CSS sprites, while the sidebar is using plain old <img> tags.)

A quick CSS workaround for this bug would be to add the rule:

img.favicon { background: none }

However, a better fix would be to change the .favicon selector in the top bar style sheet to e.g. .topbar .favicon, thereby ensuring that it won't match elements outside the top bar. Presumably, this is something like what Anna's fix will do, once it's been rolled out properly.
