What settings are you using Esper, sometimes when I have had artefacts in the image unchecking the "Equalise at each step" has done the trick for me.

I have played with the image and so far no line

unchecking the "Equalise at each step" did the trick

Well, a bit more explanations : the Dream Smoothing filter is based on the 'Smooth [anisotropic]' filter, which has been recently updated to allow parallelization.
All filters that uses it should then be updated as well (as the way it is called has changed), but unfortunately, not all have been updated.
Often, filters coming from external sources have not been updated. This is the case for Dream Smoothing, which has been done by Arto Huotari.
So, in your case, I can tell you have 2 available CPUs, and the computation has been split in 2 sub-images. If you had 4 cpus, you will have a crossing artefact at the image center.

Esper, as he4rty, same here. Not line in center, and i used default settings.
Sometimes not having the latest versions is advantageous! :hehe
