Desktop not displayed properly in fullscreen with 3d acceleration

Reported by: andrew.edmunds Owned by:

Version: VirtualBox 4.0.0 Keywords:

Host type: Windows

Description

Host configuration:

  • Lenovo T61 laptop
  • Mobile Intel 965 Express display adapter
  • Display adapter driver version 6.14.10.5218
  • Windows XP SP3
  • VirtualBox 4.0.0 PUEL

Guest configuration:

  • Ubuntu 10.10 (Maverick)
  • 3D Acceleration enabled

In fullscreen mode with 3D acceleration enabled, the desktop is not displayed properly. See attached screenshot. It looks as though each guest window is being drawn as a reduced copy of the entire desktop.

I can successfully show fullscreen video in the guest with mplayer. Switching the guest in and out of fullscreen mode with the video running also works correctly. So it seems to be only some behaviour of compiz that is not handled properly.

The desktop is displayed OK in windowed mode wtih the VirtualBox window selected. When another window on the host desktop is selected it is noticeable that the guest display is slow to repaint after being uncovered. Sometimes repainting fails completely. Possibly this is a separate issue but for now I have assumed that they are two symptoms of a single problem.

No problems are evident with 3D acceleration disabled.
