I opened an issue for this and attached the example files there:

Hello,
My team recently upgraded our GeoServer install (Linux) and found that
some of our ImageMosaic layers started displaying as "blank" or
all-white. GetFeatureInfo requests return the correct values from
0-255, but any GetMap request over the same area returns a white image.
I believe this is a bug, as it only manifests in certain versions of
GeoServer. We were able to reproduce this issue with a fresh GeoServer
config with a single-GeoTIFF store using the following files:
https://nofile.io/f/vrsudQRfAkf/20100101_N_20100101_concentration_v3.0.tif
- Works in any version of geoserver >=2.9
https://nofile.io/f/gUbhdR7ybkE/20100101_S_20100101_concentration_v3.0.tif
- Works in any version of geoserver >=2.9,<=2.10.2. WMS requests
return a white image in geoserver >=2.10.3
I believe this issue can be reproduced only in >=2.10.3 by the
following steps:
0. For each 20100101_S_20100101_concentration_v3.0.tif,
20100101_N_20100101_concentration_v3.0.tif:
1. Create a GeoTIFF store from the file
2. Publish a layer from the new store
3. View OpenLayers layer preview for the new layer
North should display grayscale data, South should be a white, empty
image. User should be able to click anywhere on either image and get
correct floating point values from 0-255 via GetFeatureInfo requests.
When requesting a GeoTIFF, the south image displays all-white while
the north image displays the correct data.
Example requests and results in geoserver >=2.10.3 (everything works
as expected in prior versions):
wms?service=WMS&version=1.1.0&request=GetMap&layers=NSIDC:20100101_S_20100101_concentration_v3.0&styles=&bbox=-3950000.0,-3950000.0,3950000.0,4350000.0&width=730&height=768&srs=EPSG:3412&format=application/openlayers
-> Blank image
wms?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&FORMAT=image%2Fjpeg&TRANSPARENT=true&QUERY_LAYERS=NSIDC%3A20100101_S_20100101_concentration_v3.0&STYLES&LAYERS=NSIDC%3A20100101_S_20100101_concentration_v3.0&INFO_FORMAT=text%2Fhtml&FEATURE_COUNT=50&X=50&Y=50&SRS=EPSG%3A3412&WIDTH=101&HEIGHT=101&BBOX=-2883031.164314732%2C-1553904.9326306523%2C-908887.7907839662%2C420238.4409001132

wms?service=WMS&version=1.1.0&request=GetMap&layers=NSIDC:20100101_N_20100101_concentration_v3.0&styles=&bbox=-3850000.0,-5350000.0,3750000.0,5850000.0&width=521&height=768&srs=EPSG:3411&format=application/openlayers
-> Fully rendered sea concentration imagery
WCS requests for the same data show no issues in 2.10.3.
Has anyone experienced these issues? It seems like a bug to me, and I
plan to open a bug based on this issue. Just doing my due dilligence
and posting to the mailing list first. Haven't found anything on
Google yet, but that could have been due to bad search terms...
Thanks!
