Have setup GeoServer to work with GeoWebCache. Apparently, I have applied
most of the tweaks for improving performance and quality, but still have
rendering issues when using Nearest Neighbor interpolation or GeoWebCache:

Summarizing, I have:

 - Enabled direct integration with GeoServer WMS, tiled=true..etc
 - Enabled the fullWMS mode, using hints=quality parameter in the URL

I have been using Bicubic interpolation because this produces good results
for basemaps when viewed as WMS. This is what I get when using WMS+Bicubic:

However, when using Nearest Neighbor+WMS, a white line pattern shows up. So
lines and labels seem to be "split". This is only a slight change but it
makes the map pretty much unreadable:

Now, when moving to GeoWebCache with Bicubic interpolation, I expected to
get the same good results as Bicubic+WMS. However, it turns out that I have
exactly the same rendering issue when using GeoWebCache.

My guess is that I am doing something wrong in the layer setup that
generates the rendering issue both in NearestNeighbor+WMS and
GeoWebCache+whatever interpolation method used.

If possible, I would like to use NearestNeighbor because it requires less
resources. I think that if I can get the rendering issue with
NearestNeighbor sorted, then the results will be good in GeoWebCache as
well. BTW, the rendering issue happens also when using Bilinear method.

Can anybody provide some feedback on what I'm doing wrong with this basemap?
