Anyone seeing intermittent "Lightning out App error in callback function : Invalid locator specified - no element found in the DOM with id=x" error with Lightning in Visualforce pages?

Most of the time my Visualforce page with embedded Lightning components (via Lightning-Out in Visualforce) work fine. However, intermittently the lightning components fail to appear and the quoted error above shows up in the footer of the page.

I'm wondering if this is a browser/desktop performance issue causing mis-timing of DOM manipulation, or something else.

Anyone got any ideas?

Hey Phil, did you ever resolve this issue? One of my users is now getting it when using Internet Explorer, but isn't happening with Chrome.

Hi Benjamin,

No specific discovery other than it was definitely happening more often on long latency, low bandwidth connections, and that is why I suspected a timing issue. IE is a much slower browser generally, so that could help suggest a mis-timing issue in the way that Lightning-Out has been implemented by Salesforce.

Since we got no feedback on this forum post we've just had to live with it, instructing users to do a browser hard refresh if they see this issue (such a hard refresh seems to resolve things generally speaking).
