From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9) Gecko/20020314 Description of problem: Certain animated GIF images cause Konqueror to eat 100% CPU. top shows X using most of that CPU usage, probably in simply updating the screen. System becomes unresonsive until I can close the window. I think this has something to do with Konqueror not having a minimum delay period for looping animated GIF. Mozilla and Internet Explorer enforces a minimum loop delay so they don't have this problem. This sample URL image loops too quickly like this. http://www.mplug.org/archive/2002/konqueror_animated.gif How reproducible: Always Steps to Reproduce: 1. Visit that URL in Konqueror. Expected Results: Konqueror should enforce a minimum animated GIF loop delay.
More information, this is a QT problem. Please read this URL for details. http://kt.zork.net/kde/kde20020222_33.html#2

The original problem is fixed, and since the fix for this particular image would need a near-rewrite of the QMovie class, it's not doable for this release.
