Are you using an ad blocker or other security extension? I see that none of the icon fonts are loaded…
Yes, I am. I use AdBlock in both Chromium and Firefox. And the same (non-default) fonts in both. Wrong icons is Chromium problem only. Fonts/icons issue is another problem. Didn’t want to mix two unrelated topics in one post.
In Firefox icons are correct:
Still, items remain unselectable in Firefox.
Disabling AdBlock and restarting both browsers doesn’t fix the issue. Items remain unselectable in both.
It’s really a minor inconvenience only. Don’t waste much time looking at it.
Edit. DE is standard Antergos Gnome.
