Public bug reported:

Hi all,

I have a host with Kubuntu 18.04 and VM also running Kubuntu 18.04.
Clipboard constantly hanging when copying text between VM and host or
within VM or within host only.

Problems are only when VM window is opened.

Same thing happens when the VM runs Windows instead of Linux.

All tested VMs were updated (and host too) and with current version of
spice-vdagent that handles clipboard copy.

I don't have such problem in Debian so I'd assume there is a bug in KDE
Plasma or in implementation on Ubuntu.

To reproduce the bug just install Kubuntu and virt-manager and create
Kubuntu VM and copy text. Time to time clipboard hangs and you won't be
able to paste.

This really makes computer UNUSABLE since it's super irritating.

Please let me know if you need more details.

Best regards,
