Update:

I did a full 17.10 reinstall as last attempt.
I can confirm the following symptoms:
- When both 4k displays are connected to the docking (displayport MST), UI login screen is already hanging (see earlier screenshot)
- When 1 x 4K display is connected it works. When connecting 2nd display after login (using Wayland), the UI is completely hanging
