I have been working with a commercial support team but we are both at a loss and have submitted a bug ticket with no solution to be found. I wanted to send out an email to the community and see if anyone else has seen or had this problem.
I have 4 image mosaic layers that I’m putting in a group together but when I do this the interpolation is not honored and the image is very blocky. If I call the layers separately they are fine. I want to use the layer group so its one call for the entire thing but need it to be smooth looking.
So if I just did one layer in the group it works but as soon as I add any of the other 3 layers it doesn’t. All created from the same raw data and put into individual geotifs per the parameters.

Sorry for the back to back emails. I just fired up anUbuntu 18.04 test server and loaded the layers on it and it seems to be working just fine. So something is wrong with something running in Centos7. With this server being in production right now I’m not sure how easy it would be for me to switch OS and move over. I am running VMs so I can make it happen it just wouldn’t be easy and I know I’m not the only one who runs Centos for applications like this.
I would be very surprized if it had anything to do with the OS that was hosting geoserver. I would suspect issue is something to do with config the instance. Are your servers running the same version of Geoserver, with same set of addins? I would also take a look at the cache settings on the layers and the groups. (Start by turning caching off completely for both layers and layer group. In production, I have caching off for layers, caching on for layer group, but turning everything off will eliminate that as source of problem).
And yes, all our geoserver instances are running on Centos servers, and I commonly use layer groups to merge tiff layers from each side of the antemeridian.

Hi Jody,
single raster layer vs groups use different rendering paths, the single one uses the “direct rendering path” which
does not go through StreamingRenderer, but uses pure JAI for better performance and scalability.
That said, if you are not able to reproduce the same issue in a different setup, something odd is going on.
I’ve just tried setting the WMS interpolation to bilinear in the server configuration, and running on the spearfish
group, the dem is interpolated with bilinear, even with high oversample (keep on zoomin in).
Also tried putting the dem in a mosaic and using that in a group, still interpolates as configured…
I’ve tested on 2.17.x, because that’s what I had handy for a 5 minute test.
Cheers
Andrea

That error normally points at a mismatch between the gridset requested by the client and the one cached by the server,
either because of differences in the bounding box, or because the resolutions are not the same.
Did you customize the gridsets in the old server by any chance?
Cheers

I didn’t have the cache layers set. That has been fixed but for some reason the capabilities doesn’t have the time dimensions listed anymore. I used to have them because my leaflet app would read it from there and let me do looping. Any ideas on that?
