[Pkg-virtualbox-devel] Bug#827990: virtualbox: Missing mini toolbar in version 5.0.22-dfsg-1

[vbdasc]

Package: virtualbox
Version: 5.0.22-dfsg-1
Severity: important

Dear Maintainer,

After upgrading virtualbox from 5.0.20 to 5.0.22, I noticed that the mini-
toolbar went missing in fullscreen mode in all my virtual machines. I tried
some of the workarounds that worked for similar problems in earlier versions
(enabling/disabling 2D/3D hardware acceleration, increasing video memory etc.)
to no effect. The Host key+Home combo still works, but I can't minimize the VM
from there. This bug severely limits the usability of VirtualBox for me.
