I've had issues with this setup from day one (documented in my many posts on this forum, sadly). I was hoping that upgrading to BigSur / the new DisplayLink driver would help, but I just started having different problems.
My main issue with the new driver manifests itself each time I share my screen via Zoom / Google Meet. My Macbook progressively grinds to a halt within 5 minutes. The CPU usage of the kernel_task process progressively goes up to ~1000% CPU usage, at which point my Mac is unusable. My understanding is that kernel_task high CPU usage is linked to the Macbook overheating...
The high CPU usage of kernal_task is due to the DisplayLink driver: as soon as I kill the DisplayLink driver application, I loose 3 of my external monitors and the CPU usage progressively goes down to normal.
I posted several times on this forum, but I only got one response from Kate / DisplayLink.

I am experiencing a very similar problem. I only have 2 monitors but the pattern is the same. I used to have the same setup using 2 hdmi ports coming out of my Macbook and it used to work just fine. Now, using a dock station with the DisplayLink driver it it is basically impossible to use.
