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.
Created attachment 202139 [details] the source of the frame that appears to cause the high CPU usage
I see the same as the OP with today's branch build: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051107 Firefox/1.5 ID:2005110708 Also the Business page at www.msnbc.com with the 'ticker tape' scroll forces high CPU usage and garbage on refreshes to the ticker that occurs each minute or so..the text over-writes itself..
