Ticket #15767 (new defect)

Keyboard capture often escapes to host when using the "Windows" key (Windows host, Linux guest)

Reported by: Ptival Owned by:

Guest type: Linux Host type: Windows


I'm not quite sure when this started happening, but it happens to me a lot now (VBox 5.1.2).

My guest VM uses xmonad, and I set it so that using Win-1, Win-2, Win-3, switches desktops. Many times, when I am keyboard-captured, and I start switching desktops, one of them will suddenly escape and do stuff in my Windows host...

How to reproduce:

  • Run a Linux guest, Windows host.
  • Set it so that your keyboard is captured in the guest.
  • Start mashing the Windows key with any other key, like 1, 2, 3, Left.


  • Within a few seconds of mashing, your host's Windows menu will pop-up.

I tested it with three different keyboards and two different machines.
