Hi fsantiago

Indeed, very similar problem.

A couple more things (some of which may be of interest to you):
- When I used the old version of the driver (v5.3.1 -- which stopped being supported on BigSur), I could connect all my monitors and I didn't experience the kernel_task high CPU usage
- However, with v5.3.1 my monitors didn't "stay in place" (I had to go in my MacOs Display Settings and readjust my monitors each time I restarted my Macbook).
- when I disconnect the DisplayLink docking station from my USB, it disconnects the external monitors that are plugging into it, but I continue to have the high CPU kernel_task issue when sharing my monitor in a Google Meet / Zoom call.
- the only way for me not to get the high CPU kernel_task grind to a halt issue is to Quit the display link driver completely.
- it has gotten to the point where I am no longer using my displaylink docking station at all. I have posted a 2 star review on amazon, which I should really downgrade to 1 star at this point, because the DisplayLink does not work as advertised on MacOS.
