GeoTIFF store with an 8 bit RGB GeoTIFF with #000000 as nodata. Published with the input transparency colour set to #000000. When viewed in WMS in a different projection, white artefacts appear around the edges of the image.
I have a pending fix for this:
but it's blocked on GEOT-5318, for which I have a PR ready:
Merged to master, and backported to 14.x/2.8.x. Due to API changes, could not be cleanly backported to 13.x/2.7.x.
Hi, so can this one be marked as solved in the 2.9.x series?
Yes. I have marked this as resolved.
