Slow performance MBP with Debian 9

Hello folks,
I've got a new MacBook Pro (2015 edition) running macOS Sierra 10.12.5 and am having similar issues with VirtualBox 5.1.22 r115126 (Qt5.6.2) when working with a Debian 9 (64-bit) / KDE guest OS instance.
- KDE performance is very very poor (2-3 lag trying to drag / resize a window, jerky rendering of desktop effects etc.)
- Any attempt to enable 3D acceleration causes major render malfunction / unresponsive Debian 9/ KDE guest
I have attached a copy of the VirtualBox startup log. Thanks in advance for any suggestions. - Chris

Several other symptoms of the VirtualBox setup I posted about previously:
- Long lag from mouse-down to window chrome state change in KDE during drag-and-drop/resize operations
- Once I have successfully initiated an operation in KDE (e.g. a window resize) it's almost as if the mouse event stream is screwed up. e.g. dragging the border of a KDE window with left-mouse button depressed will not work reliably requiring often several attempts to get a window sized/positioned as desired.

The title of the thread you posted was "

Oh sorry - I intended to reply to my own thread but made a mistake.
To clarify, these comments:

Thanks, Chris
