I documented the problem in detail at https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1815429 where you can also see VM definition. If you are able to reproduce this bug, please vote for the bugfix.
TL,DR: if you are running GPU passthrough to nvidia card and running Xubuntu in the VM, then after installing nvidia drivers you will not be able to lock the screen. The workaround is to install xfwm4 version 4.13 from Mint repository.
