I'm facing the same issue on Dell XPS 13 9380 and Type-C dock with 2 displays. Sometimes I'm seeing all 3 screens flashing, sometimes they go black but mouse pointer is visible (and it's moving). Like in the original report, it may take up to 20 seconds for screens to settle.

I think I have one somewhere, and an old laptop that can use it. Just a matter of time and priorities to set it all up.

[Desktop-packages] [Bug 1859955] Re: Long delays and repeated flashing when docking laptop with multiple monitors
Thanks. It appears the process of docking introduces three new DisplayPorts, of which two are plugged in. To debug this further I do not know the commands. It might require a development setup, unless someone knows how to log udev events. I think that's what it will be...
