Solutions for Gnome Boxes Mouse Disappearing?

Often when I’m running Boxes VM when I switch between the host OS and the VM, then back, the mouse disappears.

Shutting down Boxes and then re-starting fixes it… until I have to swing between host and the VM.

Anyone have the problem and know a fix?

Try this command to reset the mouse:
sudo rmmod psmouse; sudo modprobe psmouse

I have to do this so often on my laptop, that I have set up a custom key combination (CTL+ALT+m) to execute it.
