Ubuntu is running as guest, the host is Windows 7. The attached information was fetched from the guest os and you can see the screen resolution changes in the XorgLog.txt. I am not sure if the lockscreen issue appeared at 404655.* or 407563.*. The following entries were caused by me trying to reproduce the problem.

When I started some program in Windows (host) and accidentially changed the window size of the Ubuntu VM from fullscreen to window and back the lockscreen did not change the resolution back to fullscreen although the desktop did. As a result I was able to use the desktop as the lockscreen did not cover the whole screen. Unfortunalely, I did not make a screenshot and I cannot reproduce the described behaviour.
