System Information
Win 7 Ult 64
GeForce GTX 580

Blender Version
Broken: Buildbots Last ~48 hrs
3780158-win64
a149a67-win64
Worked: Before 2-3 days

Short description of error
When going to Sculpt Mode and doing sculpting, after exiting SculptMode and returning to ObjectMode the mesh seems as it did not take any sculpting.
After saving and reopening the file, it looks OK.
After further testing on a default scene with a scene I think the culprit is that some AutoSmoothing gets applied to the mesh. If i go to Properties > ObjextData >check then uncheck again AutoSmooth it get's fixed.
This has to be repeated after each time you go into SculptMode and exit.

Exact steps for others to reproduce the error

Create a Cube
Add Subsurf 4 Levels
Apply Subsurf / Convert To Mesh
Enter SculptMode > Change to Crease Brush with strong strngth > Apply some strokes
Exit SculptMode
... The mesh looks weird. Enter SculptMode - it looks fine
Go to Properties > ObjextData >check then uncheck again AutoSmooth it get's fixed.
This happens every time entering ScilptMode and making strokes.

I haven't been sculpting as of late so I didn't notice it earlier.
Just checked going back to older versions of Blender off buildbot, and this is present in older versions as well.
tracked it back at least to: 1cfe274-win64

This has nothing to do with auto-smooth, it’s just mesh normals not being updated when leaving sculpt mode…
