Do you mean qxl-wddm-dod by qxl-dod ? If not you can get it from
https://www.spice-space.org/download/windows/qxl-wddm-dod/
https://gitlab.com/spice/qxl-wddm-dod
The latest version is 0.15 released in DecemberYes, I've also tried that binary with the same results :-(.At least is not worst.I never experiences such terrible performances.What are you doing on the guest machine? Normal office applications?

Playing videos?

Which image compression are you using?
I use virt-manager's GUI to connect, so whatever's the default for that.
What's the quality of the network? What about bandwidth and latency?
I'm locally connected. I don't think this has anything to do with network, because with the basic Microsoft graphics driver things are normal... I mean performance is what you'd expect from emulated hardware and much better than qxl-wddm-dod...
