Mouse cursor disappears with Tahoe on second user

Nifty · Today, 07:38 AM

I’ve recently updated my MacBook Pro M1 to macOS Tahoe. After that on my main user account, everything works with display link. I could use my external display as normal.
My daughter has a separate user account. After she logged in, I needed to start the display link manager, as it was not running apparently on her user account. After starting it, the external display appeared, but then the mouse cursor was kind of frozen. But the mouse actually worked. So I could see it when hovering the mouse over the dock that the icons just moved as normal but without displaying the mouse cursor. From time to time, the cursor was shown but then was stuck again. CPU was on a very low one figure percentage. I disconnected the screen, but it still was lagging then I switched back to my user and it worked perfectly. Switched back to her user it was not updating the mouse cursor.

I had DisplayLink 12.x I believe so I updated to the latest 15.x but still not difference.

Any help or ideas? Thank!
