PIng... any updates here?

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!! :mad::mad:

So... are there any plans to support AMD Ryzen ever?

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

This also worked perfectly for me, It's a bit of a headache because it's lost when you update the kernel so you have to go through resigning the .ko file etc. However once it's done, it works perfectly.
