Simple Displacement 100% CPU Hang with Adaptive Subdiv macOS RPRv17239

Can anyone else confirm this bug for me? Blender crashes if you change Subdivision from Level to Adaptive + Displacement is on. Also that for some reason changing Subdiv to Adaptive on the right hand panel (For the object data) also changes it for the material at the same time as if they are linked.

Blender doesn't actually crash. It just goes into 100% CPU and won't break free. I tried it with Uber and I don't even get this far before it locks up. Hence the really simple diffuse shader just to isolate the bug to Level or Adaptive subdiv.
