Win 10 20H2 transparency not working with 3D acceleration

Host: VirtualBox 6.1.18 r142142 (Qt5.14.2) on Ubuntu 19.10 host, Nvidia GTX 1050 Ti graphics, Nvidia 460 binary drivers.
VirtualBox settings: display VBoxSVGA with 3D acceleration ticked.
Working guest: Windows 10 1909 edition, 6.1.18 VirtualBox extensions installed - fine until upgraded to..
Problematic guest: Windows 10 20H2 edition, 6.1.18 VirtualBox extensions installed - with default Windows settings, main menu background appears for a second, then goes fully transparent. The taskbar is transparent from the start.
Unticking transparency effects in Windows or unticking 3D acceleration in the options in the host stops the problem, but something's not right. I am not enough of a Windows nut to know if Win 10 1909 had transparency effects or not, but the main menu and the taskbar appeared fine.
