I reverted to the version of the day previous to the introduction of the 
new sun coloring.
At first I though the artifacts Melchior recognized weren't there.
However, after a second Flight  from EDNY they also appeared:

I suppose the effect wasn't that visible before since the sun color was 
much less bright then.
So contrast wouldn't be as much and it is first visible if you increase 
visibility.

Then I checked material.xml, as Eric indicated and found it is indeed 
the specular component causing the effects.
If you change it to 1 the artifacts are drastically visible on tile 
edges; with 0.1 there almost gone.
But then the specular highlights are gone of course.

Another thing I noticed is that the drawn highlights cover almost the 
entire  tile.
This might be OK for some materials, but for water there should be a 
rather sharp highlight.
Maybe this was changed and now is causing the trouble?
