The second got a AMD Ryzen Pro 4750U and the performance of the external sceens is very low.
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.
