When having many open and idle tabs in Opera, after starting the browser one of them begins a high CPU usage. This happens randomly on a random tab. After checking in task manager which tab is causing CPU issues and refreshing it all goes back to normal. This happens only in opera - haven't noticed such behaviour in Firefox.
