Virtualbox 4.3.18 has been released about three days ago, bringing many different fixes for major operating systems such as Ubuntu Linux, Windows and Mac OS X. The potential misbehavior after restoring the A20 state from a saved state has been fixed, virtualbox does not crash anymore in linux hosts with old versions of the linux kernel, a few remaining warnings in the kernel log if memory allocation fails have been fixed and the GNOME Shell on Fedora 21 is not prevented anymore from starting when handling video driver display properties.
Thanks to this maintenance release Ubuntu users have now the possibility to use legacy full-screen mode under Unity without experiencing multi-screen issues.
