I have a similar problem which is probably related to this bug. I'm running a Windows XP guest and an Ubuntu (with compiz) host. When I don't have any open windows on the guest, my gnome-panels aren't visible on the host. The same thing happens if I maximize a window on the guest.
I have to open a window in the guest (or "restore" any maximize windows) for the panels to reappear in the host. The proposed workaround only works when I don't have any maximized windows on the guest. Replacing the window manager with metacity solves the problem completely. Could this bug be related to compiz? -- virtualbox does not redraw background in seamless/compiz mode https://bugs.launchpad.net/bugs/230811 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
