Can easily be recreated, on both VBox and VMware. Disabling 3D acceleration in the settings for the VM stops this issue however. Must be some sort of issue caused by 3D acceleration.

Changing the xfwm (compositor) vblank method to 'xpresent' or 'off' resolved this for me under VMware Workstation 15.5 with 3D acceleration enabled.

Restart xfwm with vblank set to 'xpresent':
$ xfwm4 --replace --vblank=xpresent &

Restart xfwm with vblank set to 'off':
$ xfwm4 --replace --vblank=off &

Permanently set the vblank method:
$ xfconf-query -c xfwm4 -p /general/vblank_mode -s xpresent
