Photoshop: Artifacts on every layer mask and channel

Helping out a co-worker who claims that all these little artifacts showed up after she saved this file. They are on almost every layer and layer mask. They show up in the channels. They are duplicated in a grid pattern. I can't think of a good way to fix this.

Can you include a full-resolution screenshot? It is a little hard to tell what they are at the reduced size.

Do the artifacts save with the image--if you save a copy as a flattened JPG and view in a browser or OS viewer?

Do the artifacts resize when you zoom in?

In other words, are the artifacts part of the video display system or part of the document data, itself?

Does this happen with every document?

If you hide all the layers are the artifacts still there?

I am having the same problem.  How was it resolved?

It is not a video glitch. They are a part of the file. This is the only time it has happened. The artifacts are on at least 7 layers that have layer masks. If I isolate layers they appear lighter. They build together when all 7 layers are on. It is a repetitive pattern - all the artifacts look like the super-zoomed in image above.

Oh, and if I turn off the offending layers, they disappear.

If you turn off the Layer Mask do they disappear?

To me it looks like a pattern-fill was applied, or that the file was corrupted?

Was this document created entirely by hand or were parts made with a program?

I suppose you don't keep enough history steps to go back until before it happened, to try to determine the cause.

If it is really part of each layer's pixels, then I don't know how to get rid of it without erasing those pixels or recreating those 7 layers.

Apparently everything went crazy right after someone dragged in a screen shot from CAD. Before that they weren't there.

Can you repeat it with the same CAD screenshot dragged onto a new document?

Unless someone recognizes the situation, I'd guess Adobe would like to have the raw materials for repeating the issue to see if and where their software acting up, so they can fix it before the next version of CC is released.

Without having access to the raw bits that were composited into the document, to me the artifact, itself, looks like a one-inch-square tile created by scrunching a circular tree (or bush) symbol into the edge and letting it pile up pixels, and then repeating that at the left and right of a tall strip in ever smaller scales. Is that what it looks like to you, or is there some other part of the composite document that resembles the colors and circular pattern of the artifact besides the trees, perhaps an existing brush of some sort. A related question is whether the circular tree symbols are a brush?

You said it is only on the 7 layers with masks, so another question is if you create a new layer and add a mask does the pattern show up, immediately, without purposely adding any pixels to the layer? That would suggest it is tied tightly to the mask. If so, that might be a good enough starting point to send to Adobe to have them test with, if they can get the artifact to show up, easily on a new layer even though your document has had quite a bit of work done to it, already. They should be able to find the source of the artifact and maybe determine why it is there.

What version of Photoshop is your co-worker (and you) running? Is your co-worker on Mac or Windows?
