Mac Mini M1 + DisplayLink + Monterey 12.3

I've just installed Monterey 12.3 on a Mac Mini M1 16G. It has a displaylink adaptor driving 2x further displays.


Everything working well previously. Now on main (HDMI) monitor I can't resize any window. On the two extended (DisplayLink) displays I can resize as normal - can even drag window from main display to an extended one, resize and drag back. Right click on backdrop doesn't work on main display either.


I usually have a remote desktop session open full screen on one of the extended displays - this now minimises every time I open a safari window.


Things seem utterly broken and I don't see an easy route to roll back?


Mac mini, macOS 12.3

Hi thowat,


Does the same issue happen in a temporary new user? We ask because a temporary new user doesn't have any changed or custom settings, which can help start isolating an issue to see if it is system-wide or with your current user: Set up users, guests, and groups on Mac 


If you wish to go back to a different macOS, you can use Time Machine to do so (if you have a Time Machine backup from a different macOS version) or you can backup your content, erase your drive, and reinstall macOS. Depending on what you'd like to do, the articles below might be helpful to you:


Take care!
