Display anomalies after upgrade

[craig100]

Hi,

Have been using VirtualBox on Linux Mint for many years to develop .net websites on a Windows 10 guest. Today I had a windows update immediately followed by a VB upgrade with associated Guest Additions and Extensions. Now I get things like the Windows task bar background missing, Brave (or Chrome) browser address bar totally screwed (hopefully I can attach a screenshot).

The details are:-
Host: Linux Mint 18.3 Cinnamon, Kernel 4.15.0-62-generic, NVidia GPU Quadro K1100M, VB: Version 6.0.12 r133076 (Qt5.6.1)
Guest: Windows 10.0.18362

When I upgraded VB I was warned to switch from VBoxVGA to VBoxSVGA which I did, then ran guest additions.

Previous versions going many years back have been solid as a rock so not sure what's happened here.

Any advice on fixing this would be appreciated, or is it a bug?

Regards,

Craig

As well as previously mentioned, many Windows items are just black boxes (see screenshot). I'm at a loss as to where to look and I can't work any more. Please help.
