Version: 2002070508, x86 Linux (KDE) Repeatable: Every time! The above url (www.untitledgif.org/archive.html) has two images on it that vibrate back and forth when I view the page. They are the images of "Bob Stubaggio" (bob.gif) and "Genocide Cannon" (cannon.gif). This is really strange. The images aren't animated and there's nothing funny going on in the html. Several previous versions of Mozilla didn't vibrate these guys, either.

wfm, linux build 20020704 do the images vibrate if you right click and "view image", or only within the html page?

I am seeing the vibrating images also. And they are fine when using the view-image menu item.

It is ok for me now (linux 2002102908). Tom, do you still see this?
Still happens in 2002100604 on linux; I'll try out a new nightly soon... (Though to tell you the truth, I would sort of miss this bug...!)

I can reproduce this on solaris 8/sparc using nightly 2002110322. Bob and the cannon oscillate about 4x/second, generally up and down but sometimes side-to-side. I have some random observations: 1) With the web page, if I scroll the page so that part of bob or the cannon is off the top of the content area, that image stops oscillating. They keep shimmering though if I scroll them partway off the bottom of the viewing image. 2) View->Page Info->Media and select the bob gif or the cannon gif. The images shimmer in the preview area too, but only if the preview area is smaller than a certain size vertically. Try resizing the page info area until a vertical scrollbar appears in the image preview area. 3) The effect is completely repeatable. I can resize the browser window, load other pages, etc., but ol' Bob keeps dancing. I'll attach a reduced version of the web page. If I remove the center tags or h1 tags the effect is destroyed. Changing h1 to h2, or moving the h1 section outside the center tags, also destroys the effect. Moving the IMG tag outside the center tags does NOT destroy the effect.

This zip archive contains ten traces of mozilla with corresponding stack dumps. Mozilla was idle, other than animating one of the images (the cannon gif; bob was offscreen). I used "truss -l -u '!libthread,libc,libc_psr' -u '*' -T write" to trace mozilla. This causes truss to trace library calls (excluding libthread and libc) as well as system calls; it halts the process every time a write() is performed. The stack traces were taken each time truss halted the process. About every third process trace ends in a write() of about 5k to FD 6. As far as I could tell, these were the writes that caused the image to move.

ok, I'm seeing this with the URL and Kenneth's testcase. It seems to be somewhat profile-specific as well. A pristine profile exhibits the bug. regression between linux trunk builds 2002061108 and 2002061304 marking NEW

User Agent Mozilla/5.0 (X11; Linux x86_64; rv:48.0) Gecko/20100101 Firefox/48.0 Build ID 20160323030400 Closing this as WFM because I can't reproduce on the current Firefox release (v. 45) nor on Nightly 48.0a1. Being an old issue, it might be fixed in the meantime. However if anyone can still reproduce this on a current build, fell free to reopen the bug.
