Jack: I expect this is not a case of if anyone knows, but if anyone has reported this as a feature request yet.
Thoughts: - Does the problem go away if you zoom in (is the problem just the edges of the dataset bounds, or is the problem at the end of the draw area). - If you set your layer bounds to less than the whole world, does the artifact still show up at the edge of the dataset? (Or edge of the draw area). -- Jody Garnett On Sun, 30 May 2021 at 15:53, Jack F via Geoserver-users < geoserver-users@lists.sourceforge.net> wrote: > Hello all, > > I posted this question 2 months ago on GIS stackexchange, but no answer. > Hoping someone on here might know.
