Screenshots cannot be taken when selection is within the display screen of a VM (the cursor is in the zone of being automatically captured)

[Photon89]

I have found that when trying to take screenshots of VMs, if the top-right corner within the area of the VM display where my cursor is automatically captured, that I am unable to take the screenshot, simply nothing happens when I press Enter, and I have to exit with Esc, if I am lucky that will exit it, otherwise I might have to go into a TTY and end the Shutter process manually because there will be no way of getting out of it.

The VMs I'm running are in QEMU with KVM and displayed through virt-manager. I am running Ubuntu GNOME 16.04 with GNOME 3.20. My Shutter version is 0.93.1-1ubuntu1.
