Hi Andrew,
sorry, I haven't been in the forum for a while...
It is also the use of external monitors that causes this behaviour.
I tried this because of the drop-station failure in a multi monitor setup.
I use 2 external Monitors (because of Cubase, not for BIAB), one via usb3/thunderbolt and one via HDMI.
If I disconnect the monitors and work with the internal macbook display everything is fine.
I feel a bit sorry for you guys because it is nearly impossible to test every weird setup.
