OpenGL: When VM is paused, the screen is rendered incorrectly

Reported by: Technologov Owned by:
Component: 3D support Version: VirtualBox 2.1.0
Keywords: Cc:
Guest type: Windows Host type: Windows

Description (last modified by misha) (diff)

When OpenGL is active, and I pause the VM it's rendering becomes wrong. The screen is refreshed/invalidated incorrectly making garbage on screen.

Steps to reproduce:

  1. Run OpenGL application on Windows guest
  2. Pause VM
  3. Move VM window on host, and move host's applications window-frames over the VM window frame.
  4. It will result in garbage rendered (similar to "kill -SIGSTOP" to normal GUI apps under Linux)

The VM must become gray, or at least remember it's last drawn frame. VBox must be able to redraw the contents of the guest screen upon request of the Host's window manager.

Possible solution: remember the GL context and convert it to gray texture.
