315447 - rolling text causes very high CPU usage

Status: RESOLVED DUPLICATE of bug 315444

(Firefox :: General, defect)

Description

[David]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7

The rolling test at the upper right corner causes over 80% CPU usage, where IE has 1% for the same page. When the mouse hovers over the rolling text, it pauses from rolling, and CPU usage goes down to 1%. When I move the mouse, it goes on rolling, and CPU usage is back to 80-90%.

Reproducible: Always

Steps to Reproduce:
1.enter http://www.ynet.co.il (it's hebrew, but you can ignore the contents)
2.CPU usage is over 80% (with pretty good computer)
3.hover over the rolling text in the upper-right corner - CPU usage down to 1%

Actual Results:  
over 80% CPU usage

Expected Results:  
much lower CPU usage. IE uses 0-2% CPU for the same page.
