Ubuntu 11.04 guest fullscreen graphics are broken with 3D enabled

Description (last modified by aeichner) (diff)
- VirtualBox 4.0.6, Windows 7 (64bit) host,
- Ubuntu 11.04 Desktop (32bit GA) guest with 4.0.6 additions installed with DKMS.
- Lenovo T510 laptop,
- Intel GMA HD graphics,
- Latest BIOS and graphics drivers.
My goal is to get Unity working, which requires 3D support.
3D acceleration works fine in windowed mode, even when maximized. Hovewer, when I then attempt to go to fullscreen mode, the guest display no longer redraws or responds properly: it looks like it's not drawing any 3D effects, and only redraws the screen when they have ended. If I leave fullscreen mode, everything works properly again.
Sometimes, entering, leaving and entering fullscreen mode in quick succession solves the redrawing problem, but keeps the resolution the same as it was in windowed mode.
Booting the VM into fullscreen mode has the same problem.
The problem does not occur when 3D acceleration is disabled (but then obviously compiz/unity does not work).
This problem is present in all 4.0.x versions of VirtualBox (I have not tested older versions than 4.0.0).
