I was just wondering because ever since blender 2.78 normal map data would not be displayed in the final render. However it is displayed in GLSL (viewport). Below is an example of said problem.

Am I missing a new feature or is this a bug? If this is a bug has anyone else encountered this problem and is it being fixed? I would very much like to use the new features in 2.78 but this problem is really annoying me.
