Many nightly builds up to 4-6 and probably past. Open the URL in mozilla. Move the mouse pointer around rapidly inside the window in which the gif appears. Notice that the speed is faster while you're doing this than when you're not moving the pointer. This is a general problem with animated gifs in mozilla. The throbber will exhibit this behavior also if you can manage to get it to spin for long enough to test (and spinning a lot is not something mozilla really has a problem with).
can you please download a m16 nightly and check, as I cannot see this.
I can reproduce this on the 4.24.00 AM Netscape Commercial Linux build. Confirming. Good catch!

Ever confirmed: true
just a comment: The general problem with animated gif's in moz (linux) seems to be that they initially animate to *slow*! To see this how this works: just open bonsai page while the flame-gif's are animating. Load the same page in NC4.7. They "burn" 4 times faster or more in NC.
>>The general problem with animated gif's in moz (linux) seems to >>be that they initially animate to *slow*! More of a symptom than the problem. The problem is the X front end rendering code needs work. Animations suck up cpu on X like you wouldn't believe. There may be some odd dynamics with animations in tables also. Tinderbox is a prime example. -P

*** Bug 36370 has been marked as a duplicate of this bug. ***
you're right..also about strange dynamics regarding aminated gifs and cells/tables: See now on tinderbox where speedracer have 5 gifs and is the only cell with it. It's slightly slower than on NC4.7 but way faster than if 5 of same gif are in 5 different cells.
this work on a winNT platform but it hasn't tested it on the linux platform.
The URL given is unavailable (sometimes?), try: http://www.hauppauge.co.uk/html/new.html instead. This bug doesn't just apply to animated images, it also has an effect on: http://www.mozilla.org/newlayout/demo/expando.html It seems that the mousing has to be done over the page itself, try resizing the window and mousing over the desktop: no effect. Normally the expando demo uses ~12% CPU, waving the mouse about raises this to ~40%. For the hauppage page the figures are about 8% and 20%. Moving the mouse elsewhere uses no measurable CPU. Don't know what all this means ;)
This one isn't just Linux, i also get it on Windows Me. It affects the progress indicator bar at the bottom too.
All pnunn bugs reassigned to Pav, who is taking over the imglib.

Actually if you move the mouse, the animation will hiccup for a second, specifically if you mouse over xul or chrome (Kevin, peterl wanted you added to this list)
You can really see this bug well on both Windows and Linux at this URL: http://www.rpfuller.com/ugh.gif The gif also pauses when you open new windows.
I don't think that this bug is related to imglib. I've seen this bug with all animations whether DHTML, or Gifs. This makes me think its some sort of rendering bug. Maybe someone should bump this over to "compositor" to see what they have to say.
FYI, that "phenomenon" is reported in bug 69803.
I don't see any problems on testcases of comments #12 and #17 with Linux 2002012808. The animation doesn't change when I move or not move the mouse. It animates on constant speed. Marking WFM.
