Do you have a URL where you can reliably reproduce this problem? If so, please share - it'd be helpful if we could try it on a few other platforms to see if it's an issue (same problem or other weird behaviour) using Chrome for Windows or testing with Chromium.
You may want to also disable all extensions for a while - I'd be more suspicious of an extension bug than the main browser, since Chrome is almost certainly better tested than extensions. Some extensions, like ad blockers, modify the markup before Chrome can render them. That could be the culprit.
Now that I think of it, I think I've seen this behaviour a couple of times in Chrome for Windows. a refresh always fixed it, but it happened so rarely I never investigated.
