Artifacts after defringe

After I use the defringe in Photoshop I keep getting this effect, how do I stop this

Are you viewing this at 100% zoom ratio?  It's the only way to fully trust what you see on the screen.

How did you apply defringe?  It is usually used on a layer that contains an object with transparent background like this

Are you adding the sky? If yes, is it to the same layer as the rock?  If yes, that's not a good way to do it.  You should copy the rock to a new layer, and place the new sky behind it.  That avoids the sort of fringing you get from antialiasing where the two edges meet.

Apologies if you knew that.
