Thanks for checking Graeme. I was using the profile with my usual image
viewer: Geeqie, but also Firefox exhibits the same behavior.
With a medium quality profile the artifacts are still there, but for the
moment I will keep using the high quality profile generated with Argyll
1.4. I can send to you screen captures that show the artifacts if you
would like.
Best,
Alberto
