Hi Tyler,
lets first see if the konwn issue matches your case. Here is a low
resolution raster:
https://demo.geo-solutions.it/geoserver/nurc/wms?service=WMS&version=1.1.0&request=GetMap&layers=nurc:Arc_Sample&styles=&bbox=-180.0,-90.0,180.0,90.0&width=768&height=384&srs=EPSG:4326&format=application/openlayers
Zoom in on any area that has red pixels, until you get very close to scale
1:1 (yes, no kidding), and you should start seeing
white rectangles that should not really be there. Is this what you're
seeing?
If not, you can open a ticket at
https://osgeo-org.atlassian.net/projects/GEOS/summary with:
* A sample dataset to reproduce the issue
* A request (URL) making it happen
Ah, one more small thing, we don't talk business on this list, if you want
quotation for one or more changes to GeoServer
you can contact privately these companies: http://geoserver.org/support/
Cheers
Andrea
