Hello, I just upgraded MapServer today on (Ubuntu Lucid Lynx) to 6.0.0-2 from MapServer 5.6.6, and am experiencing a weird error with the bilinear rendering from GeoTiff (the underlying data store) to PNG (the display format). Whereas before there were nice tapered edges and smoothing, there is now a strange black / blue /green border around all of our pngs. I read through the upgrade documentation, and it seems like there have been a number of changes to the way in which rasters are rendered, but I can't figure out the element(s) that I might be able to adjust to get the rasters to look fabulous again. Has anyone run into this particular issue? I've attached before / after pngs.
Thank you!
