Dear ones,

This is a repost from Ubuntu's bugtracker (title changed):

--- BEGIN ---

Binary package hint: virtualbox-ose

It appears that when a Virtualbox instance changes its video mode, this causes Virtualbox to destroy its window and create a new one.

If the user has switched to a different workspace in the meantime, the new window will be drawn in the currently active workspace, effectively causing Virtualbox to appear to switch workspaces on its own.

While booting a client image (e.g. any recent Ubuntu live CD), this happens multiple times in fairly rapid succession.

This is annoying a disruptive when you are attempting to get some other work done while booting an image. I frequently click "start" and switch to a different workspace in order to do some other work while the image starts, but because of this behavior, Virtualbox will not stay on the workspace where I started it. Instead, it pops up on top of the current window, in the worst case stealing password input or other sensitive keystrokes.

Could you please check whether this behaviour still occurs with version 4.1.14 and if so, please attach a log file and check whether disabling 3D makes a difference if it is enabled?

Also, please test with the upstream version of VirtualBox.

This issue occurs on Ubuntu 12.10 running VirtualBox 4.2.6 + Oracle Extensions both with 3D enabled and disabled.

To replicate:

  1. Create an Ubuntu 12.10 Guest, including GUI (desktop) rather than just CLI.
  2. On the Host, ensure you have 2 or more workspaces. By default, Ubuntu has 4 workspaces.
  3. Boot the guest.
  4. Immediately on starting boot of the guest, you see the VirtualBox BIOS logo, switch to a different workspace using the workspace switcher.
  5. Wait a few seconds, when the Ubuntu Guest changes video mode (from Ubuntu Boot logo to X desktop, or from the VirtualBox BIOS to the Ubuntu Boot logo) it will jump to your current workspace.

The host workspace switch will occur with a Windows Vista and Windows 7 Guest too in switch from the Virtualbox BIOS logo to the operating system boot screen.
