I've used MicroDisplacement before in 2.79 and all worked fine. Now, I have this problem, that all my displacements get slanted like this (see image).

enter image description here

I am actually following a tutorial for Blender 2.79 step by step and I still get this result. The only thing I found was that the Displacement setting in the Shader tab changed from True/Bump/Both to Displacement and Bump/Displacement only/Bump Only, but it seems to be working the same way...

Can somebody help me, tell what I might be doing wrong?

In Blender 2.80 the Material's Displacement input socket accepts vectors (blue socket) instead of scalars (grey socket), which gives it more possibilities (look up "vector displacement").

To properly convert a scalar Displacement map, usually a greyscale image, and make it pluggable into the material's Displacement, you need to use a Displacement node:

The Displacement node has a "Scale" value so that you don't need to use a Math > Multiply node.
