I have also found this at 10.2. I am currently working with ESRI Canada technical support on this however I can't seem to convince them that it is even an issue. I have given my tech support guy 2 identical geodatabases where I loaded rasters into a raster dataset, 1 was a 10.1 file geodatabase that worked fine and another was a 10.2 file geodatabase that contained only "No Data" for the cell values and displayed a white screen. He seems to think this is acceptable somehow.
Not impressed at all.
