Hi

I'm sorry about your experience. Would you be able to raise your case following this article?

Additionally, could you please perform the following test?
When the problem is active, disconnect monitor from the dock but keep the dock connected to the Mac. Reconnect the monitor back to the dock. Let me know if it makes any difference. This information can potentially direct our investigation.

Thanks,
Szymon
