Default Ubuntu DisplayLink Devices crash x11 session/computer (?) sometimes (reproducible)

Hey there,

I keep getting crashes with my displaylink device(s), it happens seemingly randomly when doing things with the graphical interface, but moving a youtube window in Firefox across monitors onto the displaylink device crashes it regularly.

It seems the XSession fails, because when it starts back up there is a KWin ghost using exactly 100% of a single thread (4 core processor, 25%)/.
it flashes the Toshiba logo before entering SDDM.
In order to re-enter the X11 session, I must unplug the displaylink device. I can plug it in again after it's back in to the session.
When I Kill it with the system monitor things continue to work as normal.

The computer cannot log in to the X11 session with the DisplayLink device(s) plugged in, especially after the crash. It just stays and returns to the SDDM session.

I am also using another USB C adapter with an HDMI output, in addition to the HDMI on the laptop..

Kubuntu 20.04

Support Tool export attached. From gofanco USB 3.0 to HDMI adapter crashing x11 when moving a youtube window across screens (sometimes doesn't happen the very first time, need to go back and forth mby)

thank you!
