Display becomes corrupted when 3d acceleration is in use

Description (last modified by frank) (diff)
After running programs that use 3d acceleration for prolonged periods, the display becomes corrupted. Sometimes, but not always, VirtualBox will crash. If not then rebooting the guest does not fix the problem; as soon as a program uses OpenGL it will start again. It's necessary to power off the virtual machine to fix the problem.
I see the problem on two machines. It crops up much more often on one machine where I've installed GNOME 3 in the guest; I guess this is because gnome-shell (3.0.2) uses the 3d hardware a lot.
I'm unable to reproduce this on demand, but I can make it more likely by running Chromium (the web browser) and browsing to a page that it renders with GPU acceleration.
The first sign is that the desktop background goes black, then comes back. Eventually windows stop updating, or only update a cropped portion of themselves. Finally, the screen will go entirely black, with bits of the edges of windows occasionally appearing and being overlayed with white boxes.
The guest is running Debian with Linux 3.0.
Host is running Windows 7 x86_64; my graphics card is an ATI Radeon HD 5850.
