"Broken" 60hz image after update to 1.2 on LG Ultrawide display (HP Dock G2)

I have the same problem with the LG monitor using 2019 Macbook Pro (2.3 Ghz 8-Core Intel i9) running on Catalina using DisplayLink 1.2.
This only affected one of two LG monitors.
Downgraded back to 1.1 fixed the issue

Rotate monitor still did not work with 1.2 (or 1.1).
