MacBook Pro 2020, running Big Sur 11.6.
Using UtechSmart USB-C docking station model number UCN 3270-2 to charge MacBook and connect 2 external monitors via HDMI.
Not certain, but this problem MAY have started when updating to 11.6...
DisplayLink has taken over my Macbook's Touch Bar, asking whether to mirror displays or extend desktop. It used to pop up this message now and then, but now it is showing permanently, and is unresponsive to touch. I can't select anything or cancel it or anything. It's just stuck there. If I disconnect the docking station it goes away, and if I connect it again it comes right back.
This is a serious pain in the rear because that touch bar used to be real useful!
