Having exactly the same problem. Ubuntu 20.04.2 LTS, latest drivers installed, AMD Ryzen 3. Laptop works perfectly until I plug into the dock station, then it really slows down, everything jittering. DisplayLinkManager shows as running well over 100% CPU (between 130 and 180) if I do anything on the connected monitors. Been like this for about a year now, it's completely unusable. I've seen so many other posts on here with the same issue, unfortunately just being completely ignored!!

Moving windows redraw that slow that it looks like wobbling, parts of the window are moved others aren't. Mouse cursor feels a bit more fluid, but far from usable.
If you own a notebook with an USB-C adaptor, you should better take a look at the USB-C specification, especially if it supports USB DP 1.2 or newer. In this case you might try to look for a MST Hub/Docking station instead of using the USB way.
For MST-DockingStation you should not need any additional driver, because it is a USB-DP feature, so there should not be any reason to rely on display-link anymore.

This is STILL a problem. Clearly DisplayLink aren't bothered about this, however it seems to be affecting a lot of people. I'm more than happy to work with support etc to provide diagnostics to get this fixed.

Was facing the same issue on a 3700U with Vega 8
Was able to get it working smoothly on Arch using a patch
https://github.com/pioto1225/evdi/tree/amd_vmap_texture

Installed evdi-amd-vmap-texture from the AUR and edited /etc/modprobe/evdi.conf like mentioned on the GitHub to get it working

Hope this helps
