Compare two pictures:

Made by CO 4.6.1. You can see artefacts at the shirt. Problem saves on the entire session.
Sharpening: 190 / 1,3 / 1.0
Noise Reduction: 88 / 41
Output size: 710px

Resized from CO 100% Output to 710px via Photoshop. No artefacts visible.

  Look at the light trails.
  
  Any suggestions?

  I've got exactly the same sharpening problem Roman. Even very soft sharpening won't help this problem. My output is usally 800 px (72 dpi) and even without any sharpening my 800 px pictures have this problem. Hope CO will come with a solution soon!

  This picture comes straight from CO, 800 px, 72 dpi, JPEG quality 100%, sharpening 130 / 0,8 / 1,0

  This one comes 100% size from CO, then in PS resized to 800 px
