168439 - CPU usage at max even when page is not complex

Status: RESOLVED DUPLICATE of bug 152528

Description

[Peter Yang]

Hi, I'm a relatively new user of Chimera (just today, in fact). I have CPU
Monitor running in the Dock and a few minutes after Chimera launched (displayed
some fairly complex pages like washingtonpost.com) Chimera started using the
remaining power of the CPU, even though I wasn't doing anything.

I don't know if it helps to include that...

When I drag any window (including text box windows), I notice CPU usage goes
below 100%, to about 20%, but when I release the mouse CPU usage returns to 100%
again.

I have a iMac G4 700 MHz.
