Clone Stamp Issue - Dark Lines Appearing.
Hi Adobe Support Community.
First time posting as I have been unable to find a solution online. I am having trouble with the Clone Stamp tool. It seems to be working correctly when I blend the tool on the layer I am using it on, however when I create a copy of the layer via Focus Area dark lines appear in the sections I have used the clone tool. I am unsure why this is happening and would appreciate some help in resolving this issue.
