Strange
Supposing it is a problem with the driver, you can perhaps try the unaccelerated version of display (so it would effectively become similar to VNC performance-wise)
In 3.6 you can configure video card and protocol separately…by default QXL - the accelerated "video card"  allows SPICE and VNC, and "cirrus" - the legacy card allows VNC

you can try SPICE over cirrus…just need to allow that in osinfo config. There should be something like "os.other.devices.display.protocols.value = spice/qxl,vnc/cirrus,vnc/qxl", you can override that for all OSes or just your own. See [1]
