Plasma consumes 35% of cpu while idle!

[LordDan]

Greetings. I was liking Maui 2 at best, however, my cpu temperature was being kept high. Looking at ksysguard resources, I found that a process of plasma keeps using the processor by an intermittent rate of 35% while standing idle.
Something must be wrong ... This is just too much. Has someone seen that too?

Do you have any widgets on the desktop besides the default configuration ?
Does this 35% CPU usage stay even after a restart of plasmashell ? (e.g. ALT+F2 kquitapp plasmashell && kstart plasmashell)

What process is hogging the CPU?
In Konsole type : top
Disable background processes systemsettings/startup and shutdown/ background services
Enable one by one (check cpu)
You could make another user account and see how that compares
Stop/Start plasmashell : kquitapp plasmashell && plasmashell &
Did this happen after adding any wigets?

Does your computer run Baloo (file indexing system)? 

System Settings -> Plasma Services 

You can disable this without much loss of anything.
