When requesting a small region of a layer (backed by a geotiff store), at a resolution lower than the source image, a blank white image is returned. This was reproduces using world.tiff (attached), and the following WMS requests: This returns a grey rectangle (as expected): http://localhost:8080/geoserver/importer/wms?service=WMS&version=1.1.0&request=GetMap&layers=importer:world&styles=raster&bbox=-120.0,35,-100,45&width=42&height=21&srs=EPSG:4326&format=image/png Reducing width and height to 40 and 20 respectively results in a white rectangle: http://localhost:8080/geoserver/importer/wms?service=WMS&version=1.1.0&request=GetMap&layers=importer:world&styles=raster&bbox=-120.0,35,-100,45&width=40&height=20&srs=EPSG:4326&format=image/png
