If the graphics drivers on the system running spice viewer are relevant, it's the nvidia 304-updates. I mention this because the nature of the 'visual static' or 'visual artifacts' seems to change when moving from one to another multi-head monitor. However the missing letters remain unchanged no matter the monitor, no matter whether ending and restarting virt-viewer and virt-manager.
