Windows 7 (Seven) Aero bug with VirtualBox Additions

[@VBLinux]

Hi guys !
I talking about my problem with VirtualBox Additons.

This is my configuration :

On my real PC :

3,9 Go of RAM, 100 Mo reserved to UEFI System
Intel HD Graphics (6000)
2 CPU
Windows 8.1 Professional Editon 64-Bits

On my virtual PC :
1 Go of RAM
Unkown, 256 Mo
2 CPU
Windows 7 Edition Family Premium

In details :
I install Additions, and i select DirectX3D in experimental (for aero). All is ok.
When i activate Aero (In Personalisation), and i select Windows 7 Theme, all is blue and all the graphics are bugged. Only Windows Basic Theme and Windows Classic work perfectly. How i do ?

I find a image of my bug : Search to google this : WDDM Driver does not render desktop #9439

Thanks for trying to helping me

Aero hasn't worked in a Windows 7 or Vista guest on Windows 8.1 hosts for quite awhile. As far as I know there is no fix.
