Thanks!

Are these squares still there when you open the PNG in other apps, or even reopen them in Photoshop?  It sounds like a video card driver issue, but that would only apply if the artefacts are only on the screen, and not in the exported PNG.

 

If not video card, then it could be OS specific.  What operating system are you using?

Also, can you post some example image? Upload and embed in post, do not use attachment.

Thank you for the responses! Yes, when I do the export, the exported file has the squares in it as well. I have uploaded a screenshot of how the image looks during the export. These aren't visible when editing.

But apparently not, and I suspect they should have left the checkbox. I've seen a couple of similar cases recently.

 

Bottom line - this should be reported as a bona fide bug on the feedback site (the official bug report channel). Include as many specific details as you can.
