System Information
Windows 8.1
Nvidia GTX 660M

Blender Version
Broken: 2.75a

Short description of error
When using Cycles and the dicing rate option with true subdivison in experimental feature set, the original faces of the model get split and displaced. The dicing rate appears to work on these original faces, as it is shown by the wireframe input in cycles.

Exact steps for others to reproduce the error
Create any model, set the renderer to Cycles, set the Feature Set to Experimental, in the Object Data tab set the Displacement method to True and Use subdivision to True. Add a cycles material and in the node editor add a texture to the displacement node imput of the Material Output node. Preview or render the model.

Sorry, got caught up in the thinking. The name of the bug should be True Displacement Dicing Rate.

Please always attach .blend files here, pasteall.org is volatile storage: BlenderDicingBug.blend

BA thread: http://blenderartists.org/forum/showthread.php?372907-True-Displacement-Problem&highlight=dicing+rate+cycles

So thanks for the report, but as a rule of thumb if a feature is in experimental, it’s that it’s not considered fully working yet ;).
