For me it does not change anything changing settings in Firefox or changing Xorg-settings.
Using I-Tec dock with two monitors on a Tuxedo. If i don't move the cursor, all fine, keeping at 10 % CPU, but as soon as i'm moving the mouse, CPU usage is increasing to 60-70 %.

It was a real mess to get Displaylink up and running with up-to-date XServer 1.20.7 and kernel 5.4.24. Sometimes randomly XServer is crashing while watching movie or similar.

Furthermore i think, that hardware acceleration should exactly improve the performance, not slowing down.

My personal opinion is, that the driver itself must be improved a lot.
