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.
Don’t know why or how it was lost, but it seems common in most apps and machines that you cannot paste into a password field, even on sites opened in the browser, like my insurance company and banks.
