Unusable video w/ 3D accel enabled for Win8.1 G on Win7 H

[bgshacklett]

I have a Windows 8.1 guest running on a Windows host. I've tried to enable 3D acceleration, but it results in some very strange graphical glitches, and an unusable experience.

I have the guest tools installed, and it's using the VBoxVideoW8.sys driver, including VBoxD3D9wddm.dll. I shut down the guest and enabled 3D acceleration, then started it. After the guest is started, I get the following:

1. Display 1 starts
2. The Virtualbox "BIOS" screen is shown.
3. The Windows loading screen is shown.
4. Display 2 appears.
5. Display 1 is orange with a couple of grey rectangles

Step 5 (Before Logon Screen)

6. Display 2 is Purple, the normal color it should be at this point
7. I Click display 1, which normally results in wait screen sliding up to reveal logon screen.
8. The orange screen slides up to reveal a black screen.
9. Typing password and pressing enter results in something that almost looks like my desktop loading. (The yellow boxes are windows sticky notes.)

Step 9 (After Logon Screen)

Clicking the start button results in a black screen.


Here are my display settings:

Any thoughts would be appreciated. Things work well without 3D acceleration, but it's a little slower than I'd like.

With the guest shutdown, attach the vbox.log for the guest.

I currently don't have 3D enabled, as I need to use it. Should I shut it down, enable 3D, go through a startup/shutdown cycle and then pull the log?

[loukingjr]

I would enable 3D, start and stop the guest, then pull the log.

Alright, I've attached both the VBox.log and VBoxStartup.log files. These are contain a full startup/shutdown cycle with 3D enabled.
