I finally had this issue come up again today, and I'd like to track down what's causing it...

Occasionally when saving/exporting a large PNG image (8000+px x 8000+px) with transparency (via photoshop CC) I'll discover some strange layering going on with the exported file...
(Left and right are both the same file)

Initially these files look fine. I only see the issue when Windows Photo Viewer "fails" to load the transparency and decides to just use a white background. (As shown above. Driver/Windows 7 issue? Usually only happens when opening multiple files.) However when uploading them to sites like imgur/facebook, I am presented with the grossly layered version.

So my first question is: What is causing this?
My second question is: How can I fix and avoid this?
