CentOS 7 Guest Window moving/detaching issue

I am not sure when this actually started to happen, but a very curious issue started to creep up. This is currently on MacOS High Sierra with all security updates installed. Was on VirtualBox 5.1.18, but just today upgraded to 5.1.22 in the hope it was clearing the issue, though it didn't.

When I launch the CentOS 7 VM, regardless if I login or stay on the login screen, and I grab the window title bar to move the VM to another location on the screen, the content of the window stays put where it launched, while the window, with the title bar and borders with an empty content moves.
Clicking anywhere in the actual content results in nothing happening, but clicking in the empty, moved window at the location where things would be triggers the action in the content part of the screen.
Very hard to describe in words , so here is a link to a short video showing the behavior. https://1drv.ms/v/s!AmTCPpjAMeTlkHUftFdxaJAJs4AA

I've been running this VM for a while through various point releases and don't recall having run into this previously.

P.S. A VM with Fedora 28 behaves normally (with xorg, not wayland) with similar settings.

This is a known issue with High Sierra. See #17168: VB display frame and content are no longer bound in High Sierra (osx 10.13) for details of the available workarounds.

Thank you Andy

appreciated. My search had come up empty. Interesting fact is that Fedora 28 with 3D enabled is not affected by this, so not for all guests like one poster on the bug report posted.
