Displayport screens keep going blank & keyboard repeating issue

Hello, I'm having an issue which I've now been able to reproduce on three different displayport docking stations (two plugable 6950s and one unnamed).

I have two displayport monitors connected to the dock, which is connected via USB-C to my asus ux507vw laptop.

Periodically, but usually during a video conference, both screens will go black for a second or two. It seems to be random, no spikes in temperature, CPU or memory load when it happens.

My other issue is when I use a USB keyboard directly plugged into the docking station, it'll 'freeze' for a split second, then 'catch up' but with a bunch of repeated characters and sometimes entire words missed.

I've updated my thunderbolt drivers, firmware, got all windows updates, tried multiple versions of the displaylink drivers both from the vendors and displaylink, and nothing seems to have resolved it. Have updated laptop bios, and disabled USB suspend.

Completely exhausted all options with Plugable support.

My laptop is using the intel integrated graphics but also has an nvidia 960M gpu. I have not yet tried forcing it to use that.

Is there anything else I may try? Desperately trying to get this resolved.
