Konqueror handles some scrolling displays fine and others cause X and konqueror to go to 100% cpu usage.  I find this very irritating. 

http://www.theglobeandmail.com/ has a scrolling list of clickable articles.   X runs at 1 to 3% while I'm reading this page.

http://www.msnbc.msn.com/id/3032072/ has a scrolling list of stock tickers.  X runs at 1 to 3% while I'm reading this page.  So far so good.  If I click on "Toyoto profit boosted by strong NA sales" and thus go to http://www.msnbc.msn.com/id/11214812/, the combination of X and konqueror go to 100% cpu usage.
