Title:
hud-service consumes all the cycles on my CPU
Status in The Application Menu:
Fix Released
Status in The Ubuntu Power Consumption Project:

Status in “indicator-appmenu” package in Ubuntu:

Bug description:
hud-service is consuming every available cycle on my CPU. I have a
dual core Atom 450 based netbook - typing phrases such as "image
filter" pegs the first CPU to 100% running hud-service and the second
CPU pegged at ~30-50% running compiz. When I stop typing this CPU
consumption continues on for several seconds afterwards.
This is an insane amount of CPU cycles being consumed.
Attached is a spreadsheet showing CPU consumption. The data is based
on a 2 CPU system and the measurements show total CPU consumption for
each process. Since two CPUs = 100% cycles, a 50% measurement is
basically 1 CPU totally saturated. As one can see, hud-service and
compiz are together using ~70-75% of all CPU cycles for several
seconds.
