Short description of error
Blender freezes when trying to initiate preview render while using adaptive subdivision/displacement node in experimental feature set with either small displacement scale or small dicing scale.
Exact steps for others to reproduce the error
http://pasteall.org/blend/index.php?id=51468
For example:
Preview render does initiate with displacement node scale value at .2 and dicing value at 1.00, but freezes if displacement scale value is set to .1. Blender will not freeze if displacement node is set to .1 and dicing value is at 3.00, for example, but will freeze if dicing value is set to 2.00.
