Only when the page is on top, not when minimized. Reproducible: Always Steps to Reproduce: 1.visist http://www.lurkhere.com/~nicefiles/index.html 2. 3. Actual Results: 100% cpu usage and a laggy mouse Expected Results: less cpu usage :)

Not 100% CPU usage on GNU/Linux but around 50% :) It's the ugly animated GIF file on top of the page! -> right-click on the gif and select: Block images from this server -> reload --> now you have 0% cpu usage.. Maybe the gif doesn't have pauses between the frames? Then it would be logical that we got so much CPU usage...

only happens when the picture is stretched / resized by browser, actual width is 800px, picture is streched to 100%. please adjust summary, add keyword perf. there might be a dupe out there

-> Imagelib (see 100% CPU with win2k and 0404) There are a few other bugs about too many CPU on some pages...

Think this is a dupe of bug 86319.

we have too many of these types of bugs laying around. Duping to 86319. Reopen if you feel I'm in error. :) *** This bug has been marked as a duplicate of 86319 ***
