Default DisplayLink mirroring/extended mix after Catalina Update

Hi,

I have a 2014 Mac Mini with 3 FullHD displays attached (HDMI, DP and one attached via Dual Display USB3 adapter using the HDMI). Mac OS is upgraded to 10.15.1.

The DisplayLink connected display mirrors the contents of the HDMI display but the mouse behaves like it is on an extended display (I can move the mouse across the screen like on an extended display and wiggle it to make the mouse pointer bigger). Mac OS even opens programs on the "extended" display that can't be seen or used.

The kext (5.2.54) is loaded, DisplayLinkUserAgent has permissions in Screen Recording and Accessibility (Bedienungshilfen).

I tried:
I reinstalled the 5.2.1b3 DisplayLink drivers.
I downgraded them to 5.1.1 (and reinstalled 5.2.1b3 after the display didn't even start).
I started recovery mode and rebuilt the system cache.
Nothing helped.

Best
Sven
