Wrong translucency with 3D acceleration on?

[dnordenberg]

Hi
When I enable 3D acceleration my start menu looks like this:

vbox.jpg (127.67 KiB) Viewed 1021 times

Host win10 20h2 intel UHD graphics 620 card driver 27.20.100.9664 virtualbox 6.1.32.
Guest win10 21h2 latest guest additions, 256MB video memory and 3D acceleration.

Looks fine without 3D acceleration but graphics are slower. It looks like translucency is full on when it should be semi translucent. Something I can try to fix it?

Kind regards
David

Windows 10 Transparency does not work well when 3D acceleration is enabled.

disable Settings > Personalization > Colors > Transparency Effects in your Windows 10 VM.

unactivated Windows 10 has the same setting here:
Ease of Access > Display > Simplify and personalize Windows > Show transparency in Windows
