I have a brand new X1 Carbon 6th gen with the Ultra dock. I've attached an HPZR30w monitor to it but it flickers about every 5-10 seconds. I've run all of the driver updates for each piece of hardware and all of my software updates as well. Connection cable is a high speed display port to display port cable.

I have exactly the same problem with a 5th gen. Updated all the drivers and firmware yesterday, including for the USB-C dock.
I am connecting to the monitor through USB-C.
The blinking happens more frequently when the dock is connected, but does still occur when it's not.
I took a video of the problem I am seeing: https://photos.app.goo.gl/hK7YcmxEouJhgy8p8

I managed to resolve the issue by replacing the USB-C cable between the laptop and the dock.
I was using a non-Lenovo one.
I am now using the supplied cable and I have had 3 days without any flickering.
