Create new image - possible bug

[Sharonjoy]

I have created many patterns using 'create new image' in libraries, by simply painting multicolor stripes.  This usually produces clean, vibrant patterns.  All of a sudden there are dissolve looking patches in an otherwise clean pattern.  I am using 23.01 just updated this morning.  I am using a hard round brush with everything set to 100%.  Any ideas on what I may be doing wrong?

Sounds like the blend setting for your brush is set to something other than Normal:

Or try resetting the tool: https://helpx.adobe.com/photoshop/kb/basic-troubleshooting.html#tool

Thank you for the suggestion.  Blend mode has been set to 'normal'.  I reset my tools and am still getting a dissolve effect. I have attached an image with an example.

Me again.  I tried using the same stripes in Adobe Capture on my iPad and the result did not include the 'dissolve' looking patches.  Could it be a bug in my desktop (Windows) version of Photoshop?

Its possible. I have no idea.  I'm not on Windows, but I'm going to try to see if I can replicate it.
