OK, so this is what I suspected we might be doing -- certain functions called
from device emulation (so on the CPU thread) end up calling in to the cocoa
UI DisplayChangeListenerOps callbacks, which at the moment are written
to directly call OSX functions. But only certain guest behaviour (in this
instance a guest resizing the display) causes this, so a lot of guest
use cases will work OK even on Mojave.

Yep. If you could test the patchset at
http://patchew.org/QEMU/address@hidden/
and confirm that it fixes the problem that would be great.
