Maybe you can try the lastest virtio-win-0.1.133.iso :
<https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/latest-virtio/virtio-win.iso>https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/latest-virtio/virtio-win.iso

Or try to reinstall the latest spice guest tools 0.132 :
https://www.spice-space.org/download/binaries/spice-guest-tools/spice-guest-tools-latest.exe

Why don't you upgrade qemu-kvm to qemu-kvm-ev ?
