Short answer, yes.

Longer answer, yes in some circumstances, but it's a bug.

Another answer, not if you use libvirt and virt-viewer :-)

When using the SDL backend (i.e. instead of qemu-kvm -vnc), if you
switch workspaces using Ctrl-Alt-Arrow, then SDL tries to grab the
pointer and fails and keeps retrying until you switch back to the

Fully gory details, here:


What's preventing this from being fixed is the patch getting upstream.

We don't recommend people use the SDL backend, really. The VNC backend
is far better tested.
