@Bill (franksmcb) (franksmcb) This is a bit broader. VirtualBox is still affected. I use 5.1 because of 25 VMs inside it.

End of quotes. I would recommend to test any modern VirtualBox (according to https://www.virtualbox.org/wiki/Download_Old_Builds this means >= 5.2) with non-VMVGA video driver to reproduce the issue.
