Comment 13 for bug 1800196

Summary: a feature is not working: copy/paste works initially as expected but then fails.

Kubuntu 18.04 host and various other Ubuntu 18.04 and 18.10 flavors as guest.

I don't see any slowdown but copy/paste initially works between host and guest (either way) and then stops working altogether
- between host and guest and
- just in the guest and
- just in the host.

I have to shut down the VM to be able to copy/paste again in the host.

Seems very similar to https://gitlab.freedesktop.org/spice/linux/vd_agent/issues/9 but without the freezes reported there.
