Broken display wheb 3D acceleration in on - VBoxSVGA, unusable Windows 10 system menu, slow system

Description

Also reported in forum:  https://forums.virtualbox.org/viewtopic.php?f=6&t=100229&p=486384#p486384

Issue: display defects, visible mainly on Windows 10 system menu and main system bar showing strange transparency and rendering issues. Please see attached screenshot.

Options from Windows system menu doesn't react on clicking. The whole system menu is unusable. System has to be switched off externally. System is also booting much slower and feels sluggish. Some applications are usable, like Firefox.

VirtualBox version: 6.1.14 (latest) but also observed with older versions 6.0.x

Host: Windows 10

Guest: Windows 10

VirtualBox both host and guest extensions installed, same version as above.

Setting -> Graphics Controller: VBoxSVGA

If I choose anything else, like VBoxVGA or VMSVGA or even None, system complaints "Invalid settings detected" and prevents starting. So I'm stuck with VBoxSVGA.

Issues appears only when 3D Acceleration is on

When 3D Acceleration is on, guest VM runs fine and seems to be usable.

Same here. Host is Kubuntu, Guest is Windows10. Will this ever be fixed?
