Thanks for the answer. I can see the problem, the solution is, however, a bit unsatisfying. Seems to be a problem of many viewers..

Best,

This is a duplicate of bug #44181 and possibly bug #45881. The problem is actually in the ghostscript viewer which is applying anti-aliasing to the lines of each triangle making up the surface. See bug #44181 for ways to turn off anti-aliasing in the PDF viewer.

For graphics toolkits qt/fltk when printing a contourf plot to a file (pdf/png), the file will show the lines of the patches of the underlying surface fill/triangulation.

Result is attached. Unfortunately I have no possibility for testing with the current dev version.

gnuplot toolkit does not show this issue.
