Additional Information
We apologize that we were unable to address this issue within the current product support cycle. If the issue continues to affect your work in a supported release, please contact Technical Support.
Workaround
Within the Mosaic tool, specify the Ignore background value and the Nodata value to be 255. But this will replace all 255 valued pixels to NoData if there are any within the raster dataset, apart from the raster dataset’s borders. So this works only in some cases.
