Hi Neil,
I have faced this issue with KDE. You have to change video driver (Graphics Controller) for your virtual machine to be VBoxVGA (or may be VBoxSVGA) but _not_ VMSVGA on VirtualBox. If you are on KVM (Virt-Manager?), it would be VGA not QXL.

This is for KDE only; other DEs I used did not exhibit this issue. Don't know the technical details for this issue.
