I am sure not many admit this, I was mistaken. Deactivating W3 fixed the problem, but when I removed Smush, I no longer have the issue. As I optimize images before uploading Smush gave no benefit.

Just to mention one thing. Sometimes after cache purge, Chrome desktop will display mobile version of image above masthead. Firefox ok. It just requires another purge.

Thank you for your response. I will have to continue to trouble shoot as first attempt failed.

Great plugin though. I will report back when fixed.
