[Bug 1688364] Re: Non existent host causes 100% cpu utilization by systemd-resolved and dnsmasq

[Fodder]

you are correct:
I am running desktop not server
I am running Network Manager
IP and DNS come from DHCP

I'll try the workaround and let you know.
I'll also fiddle with Network Manager and see if I can sort out what is going wrong
