As I've already said above: it's all about external graphic adapters. In 10.13.4 Apple began to provide native support for external GPUs. They have rewritten large parts of IOGraphicsFamily.kext, what brings us to the point, that all virtual graphic adapters are now unusable.
DisplayLink has reached some progress using AirPlay Technology, but since Mojave beta 3 it's broken.
