Details

I'm using a nov16 nightly of mozilla. Mozilla slows to a crawl on this site.
Even after it is loaded. This is under linuxppc, I belive this has happened on
an x86 M18 also.
I'm seeing this as well on a 2000-11-18-20 build on NT4. Mozilla is taking all
CPU cycles it can get.
someone want to testcase this one. Over to Layout.

I've narrowed down the HTML to a single table plus the images, and put it on a
page at http://cheeze.org/test/ -- please take a look. CPU is definitely spiked.
Seems to be related to loading the small GIF images; if I comment out half of
the images, the CPU spike is cut in half.

These images are animated GIFs, each animation frame being exactly the same.
(Don't know why anyone would do this ...)

So pressing stop reduces the CPU load to nearly zero.
Before I pressed STOP, Mozilla kept repeating the GET requests for the images
over and over. That shouldn't happen.
Is there a Linux for Macintosh? ;)

I also see this on w2k.
OS: Linux → All
Hardware: Macintosh → All
"Is there a Linux for Macintosh?"

Yes there is. I'm writing this using mozilla running on linux running on an ibook.
Using the specfied URL, I can't reproduce the problem in the 12/12 branch build.
Checked under Mac OS 9 and Linux Redhat 6.0.

I think this bug needs to be reopened. I'm not sure how you failed to see this.
I go to this page and mozilla slows down, this is on a Dec 15th build on redhat
linux 7.0. This also happens on a December 12th build on LinuxPPC. Other people
have verified that this happens on windows2000. Mozilla slows almost to an
unusable state and under linux the mouse cursor blinks all the time. If I open
top I see mozilla using 100% of the cputime. I can't believe you would just
ignore this serious bug.

This doesn't work at all - takes all CPU it can get. Reopening.

Resolution: WORKSFORME → ---
Confirmed problem still exists with linux build 2001020108 for the given URL.
This seams very similar to bug 52798.

What does this bug have to do with flashing/reloading graphics? I fail to see
the connection.
In response to the previous question this has to do with the fact that both
these bugs were caused by too many reflows. 
Mozilla kept on rerendering the page. This has since been fixed. If you go to
the site with a recent build you will notice that mozilla remains reponsive and
consumes about as much cpu time as it would on any other page. Hope that made sense.
