Default Very low performance with AMD Ryzen Pro 4750U

I bought a Club Dual 4k Dock (Displaylink):

I got to notebooks, one for work, one for private, both running Ubuntu 20.10
The first got a Intel® Core™ i7-10710U Processor and the dock works well.
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.
