It has a Intel HD Graphics 3000 384 MB graphics chip. I have a Windows 7 Professional 64bit guest with VirtualBox Additions installed, and 3D acceleration enabled (with the WDDM driver installed). I have provided the VM 128MB of video memory, as required. When I enable the Windows 7 Aero theme, all I can see is a blue background. I am unable to see the desktop or any of the open windows. However the mouse cursor is still visible. Please see attached screenshot. The machine does not crash, and I am able to switch back to Aero Basic. I suspect this issue is related to the Intel HD Graphics 3000, rather than the fact that it is running on a Mac. On my other computer (A Windows 7 64bit host), running an NVidia 9800GTX+ this problem does not occur.",defect,closed,WDDM,VirtualBox 4.1.0,fixed,"aero, wddm",,Windows,Mac OS X
