Seems some people here are using the DisplayLink driver offered by the company for USB3-based DL-devices. I ran into this bug using the udl driver, since I'm using a DL-device based on one of the older USB2 DisplayLink chipsets. Confirmed the problem in Mint 20.1 and Ubuntu 20.04.2. In Ubuntu, I also tried Wayland but couldn't get DL working there at all.

Some people here have stated that it helped running one of the screens with VGA or HDMI. Didn't help me though.
