XFCE black screen after fresh install Radeon RX Vega 10

[fabsen]

Hey,

I bought an Acer Swift 3 Ultra Thin (SF315-41-R7NP) which has a Radeon RX Vega 10 mobile in it.
The first issues arose starting the live current USB Boot. Windows/Buttons usually had pixel errors which disappeared after some time/mouse movement.

However, I managed to install manjaro with the free GPU drivers. After restarting into the new system, lightdm loads fine but after entering my credentials only a black screen appears.

Installed PCI configs:
video-linux, Version 2018.05.04

I tried to follow the instructions, outputs are:
xfcefail.log is empty;

(I hope that the photo is readable)

Does anyone has a clue what is wrong?
