I have a number of VMs which I run under Gnome-Boxes. After recent updates the Fedora 34 ones no-longer allow me to paste into the password screen at login. If I create a clean new F34 VM from the downloadable ISO I can paste the password into the login screen but if I apply the updates then this capability is lost.
The version of spice-vdagent does not change with the update
The machine hosting the VMs is running Fedora 33 with all updates
Once logged into the VM there are no issues though.
