macOS Catalina 10.15 Beta and Dell D6000

I have exactly the same setup and the same issue. I also had to downgrade to 5.1.1 due to an issue with 5.2 only being stable for a few minutes.

After mirroring and un-mirroring with 5.1.1 all works well on both monitors and the laptop screen (three screens total) but if I un-plug the D6000 I have to repeat the mirroring trick to get the third monitor working.
