Just encountered this issue after upgrading to Cura 4.13.1 on MacOS Big Sur. Model selection works fine on main Mac (Retina) screen, but cannot select models with the mouse on secondary screen. Additionally on second screen the zoom and rotation controls seem centred off screen, so when you zoom in and out the model and build plate wander off screen. On the primary monitor they behave as expected. I'm thankful to those who posted their observations in this thread - saved me from making unnecessary config / install changes. Cheers.
