Public bug reported: hud-service is consistently taking > 10% of CPU time, which is more than compiz. This is a high proportion of a reasonably beefy machine (i7 quad-core 1.87-3.2 GHz). I have used the HUD in this session, but it this CPU time is being spent even when the HUD is not actually in use.
