Mine had some weird behaviour but nothing a reconnect or reordering of
commands couldn't fix.

The displays are connected via HDMI and a DP->HDMI adapter. I got my
desktop PC connected to the DP ports of the monitors. The dock uses the
HDMI ports.

I booted into windows and updated everything. Including thunderbold and
dock firmware. Nothing changed. Still the same behaviour.
I'm also back on the newest nvidia driver (435.21-4).

I'm out of ideas. I could try to boot without the nvidia. maybe it
works with only intel. But I'm not sure if that is even possible. Ports
could be wired to the nvidia card.
