Video problems with windows guests on Windows 7 RC host

Reported by: felipe.aburaya Owned by:
Priority: critical Component: 3D support
Version: VirtualBox 2.2.2 Keywords: video driver colors bug windows guest
Cc: Guest type: Windows
Host type: Windows

Description

Host OS: Windows 7 RC (x64) - US english

Guests OS which the problem occurs on: Windows XP SP3 (x86, pt-br) or Windows Server 2003 R2 (x86, en-us)

Defect: The windows guest seems to be broken, with the video card only able to show colors with a range of 4 bits. The vbox 3D acceleration support is enabled. When this feature is disabled and the video driver is rolled-back to the windows standard driver, the appearance backs to look normal. For now, i am not able to use any of the video features of the vbox vm additions, like the resizable monitor resolution or even the full-screen.

Observations: The problem wasn't been observed when the host was Windows Vista SP1 (x64, pt-br) regardless of vbox 3D acceleration support being enabled or not, or when the guest was a Linux Ubuntu 9.04 (x64) with vbox 3D acceleration enabled.

Other information about the virtual machine: ACPI enabled, AMD-VT enabled, 32 MB of video memory

Hardware of the host: XFX NVIDIA 8600GT 512MB - driver version: 185.81 (beta), AMD Athlon 64 X2 6000+
