[HtoA] Autobump not working when using Layer Shader

Hi,

I have a simple shading setup where I'm using a Layer Shader to define the look of my brick wall. First layer has the base brick, one layer is the joints and the last one are leaks.
This Layer Shader is only plugged in the Surface input in the Material Output node.

For displacement, I use some maps but NOT in a Layer Shader, just combined together in a Switch RGBA.


The autobump works fine, until I plug the Layer Shader in the Surface input. If I only use one of the layer directly plugged in the Surface input, it works fine.


My guess is, in order for the autobump to work, the latest node before the Surface input has to be a Standard Surface?


Thanks

Update: autobump works if only one layer is enabled (or if there's nothing in all other layers).

Update #2 : it only happens while rendering on the GPU, CPU works fine!

So with GPU we cannot render autobump in SSS?
