Originally asked about this here: http://osgeo-org.1560.x6.nabble.com/white-edges-appearing-around-GeoTIFF-image-td5262381.html#a5264399 and was advised to create an issue here.

The attached images show dashed lines (of empty space I think) when reprojected. I have attached the following:

CHDE_RS2_2307_1_25904.tif: image that has horizontal line near the top
CHDE_RS2_2307_1_25904_with_whiteEdges_screenshot: Due to GEOS-7270 - Edges of image with NoData have white artifacts when reprojected Complete , there are white edges around this image, and the white edges seem to align with the dashed lines.
CHDE_RS2_2307_1_25904_screenshot.PNG: screenshot showing the horizontal line when I previewed it in Geoserver. I noticed that if I change ‘Tiling’ to ‘Single Tile’ then this issue does not appear.
CHDE_RS2_63045_1_32225.tif: image that has vertical lines on both sides
CHDE_RS2_63045_1_32225_screenshot.png: screenshot showing the vertical lines

If someone can help to test to see if this is reproducible, that would be great!

Thanks in advance.
