Thank you for contacting Plugable support! Sorry to hear about this issue. I’d be more than happy to assist you.
Since these displays are connected directly via DisplayPort, I wouldn’t expect you to encounter this sort of behavior. Normally, this kind of behavior is only seen on occasion when using a DP to HDMI conversion for the displays.
We have a troubleshooting tool that helps us find out what is going on in situations like this. Please plug the dock with your displays attached into your computer, then go to this page and follow the instructions there:
If possible, I’d like to gather diagnostics from the system while it is in a broken state.
Also, can you confirm you’re using the Thunderbolt 3 cable the dock shipped with? Or if you’re using a third party cable?
Please don’t hesitate to let us know of other questions.
Thanks again for contacting Plugable support and best wishes!
