Photoshop layer mask feathering strange pattern in mask

Using Photoshop when I use a tool to circle an object pick an adjustment layer and then feather the mask a strange random pattern appears in the layer or another layer that has a feathered mask. This problem has been consistent for over a year on two computers using Photoshop CC current version with a PC. The problem happens very soon after I complete the layer and start another task. To remove the pattern I have to delete that layer. Any help to resolve this would be appreciated.

Garry I'd be interested where that glacier is?

Also, another good thing to do would be:

Alt-click (Windows) or Option-click (Mac OS) the layer mask thumbnail to view only the grayscale mask.

Do this when you see the odd patterns, and post a screen shot of the greyscale mask.

Hi Gary,

I've moved this discussion from Photoshop Fix (mobile app) to the Photoshop forum.

To better understand what is happening, please show a snapshot of your complete workspace including the Layers panel. Also please try to capture the screen shot as you’re feathering the mask.

Thanks, Another photo with black squares on both sides that are a little hard to see plus the layer panel with the white boxes showing in brightness/contrast 2. I was working in brightness contrast 3 and the shapes just appeared in 2.

As a troubleshooting step, go to Preferences Performance - uncheck Use Graphics Processor and restart Photoshop. See if the problem re-occurs with that off.

Dave,

I thought the Graphics Processor was the answer but today using a different Dell computer with the Graphics Processor not checked the lines appeared again in a new file. I was again using a mask on the brightness/contrast adjustment layer. The lines/boxes appeared shortly after I was done with that layer and while working on something else. I have attached photos of everything I thought would be helpful to see this issue. I did include photo of just grayscale mask on adjustment layer. Any help would be appreciated. Is there some other place to post or email this issue and photos to get additional help? Thanks, Gary
