Bug in vboxguest: After commit Merge tag 'char-misc-4.17-rc3'

[damian]

Hello together,

after commit "Merge tag 'char-misc-4.17-rc3' d8a332730e757129e70675679f2b2a03f1ecf65e my virtualbox with Ubuntu 16.04 no longer works correctly.
The focus on a window for example "terminal window" only works very delayed. Or a move of the window with the mouse isnt possible. 
I reverted the commit 'd8a332730e757129e70675679f2b2a03f1ecf65e' and now works all normal. 

Best regards 
Damian
