Switching off seamless mode makes VB window disappear

Reported by: dimitris Owned by:
Priority: major Component: GUI/seamless
Version: VirtualBox 2.2.2 Keywords:
Cc: Guest type: Windows
Host type: Linux

Description

Host is Kubuntu 9.04, guest is XP SP3 with 2.2.2 guest additions.

Steps to reproduce:

  • Start guest; it was last not in seamless mode, so it starts in its own window.
  • Host-L to go to seamless mode.
  • Host-L to go back to its own window.
  • Guest window doesn't appear, and neither do any programs' windows that were displaying on the guest's desktop.
  • VB is still sort-of responding: If I "explicitly" switch to the VB window using the KDE taskbar, and then press Host-L, VB switches back to seamless mode.

I originally reported this using the Intrepid build. I noticed there are Jaunty-specific builds available on the download server, so I installed that instead. The problem remains, with one apparent change:

When I switched from seamless to normal mode, I had a command window open on the guest's desktop. That was displayed now, but cropped smaller than its size and much smaller than the VB window size.

I have exactly the same issue with the same system: Kubuntu 9.04 with KDE 4.2.2, no matter whether compositing is enabled or disabled, X.Org X Server 1.6.0.

When I disable seamless windows, the parts which were transparent in seamless mode stay transparent, just the windows size is fixed. I have to reboot the system (which is hard as I have to make sure the right parts of the screen are actually shown when disabling seamless mode) to fix the issue.

just the windows size is fixed.

I just noticed that even that is not done correctly: The menu bar at the top and the icons at the bottom do appear, but the window does *not* get a title bar after leaving seamless mode.

I have more or less the same problem. With a Windows XP guest (with the taskbar at the top) when I switch back out of seamless mode, all I can see is the outline of the taskbar in dark blue and the outline of the full VB windows as a very light transparent box, but no menubar, title bar, taskbar or window edges. With a Ubuntu client I cannot see anything but the transparent box. In both cases I have to use "VBManage vmcontrol <vm> poweroff" to shut the vm down.

This is on a Kunbuntu Jaunty 64 bit host.

This problem is still present with VB 2.2.4.

I can reproduce this problem on VirtualBox 2.2.4 and 3.0 on Ubuntu 9.04 (log attached).

I can confirm similar behavior in 3.0.8 on archlinux in both Windows XP and Windows 7 Guests. To ensure that the behavior is the same: switching to seamless mode works fine, switching back to windowed results in a loss of large portions of the window and no window border. The only way to recover is to switch back to seamless mode or to save the state and resume.
