Hi support and everybody!
I have a skewed image with DisplayLink DL3900 chip (Fujitsu PR08) and Onyx Boox Max2 connected as a monitor with a preferred 2104x1560 resolution.
The DL support tool output is attached.
I have a dual boot system and this issue only exists on ubuntu 18.04. When I boot Windows 10 on the same hardware, everything works fine.
