54673 - Image sequence runs roughly

Status: VERIFIED WORKSFORME

(Core :: Networking: Cache, defect, P3)

Description

[peter.harlow]

From Bugzilla Helper:
User-Agent: Mozilla/4.72 [en] (WinNT; U)
BuildID:    2000092808

In this page, there is some javascript to change (cycle) one of the images (the 
centre one of the first row of 3). This runs erratically in Mozilla.

Reproducible: Always
Steps to Reproduce:
1.Open Page
2.Allow images to load
3.Watch result on centre image of first row of 3.

Actual Results:  The image cycling runs roughly - images half load or bits of 
black render with occasional images popping up.							

Expected Results:  The image should change to another every 3 seconds.							

Now this could be over-ambitious scripting, but it does work well in IE and 
Netscape. (Although Netscape required the kludge of loading the images into the 
2x2 dots at the bottom of the page).
It also works with other browsers such as Opera, StarOffice and kfe with just a 
single image and no cycling (by either using the noscript or just the initial 
conditions).

Browser, not engine. Reassigning to Browser-General -

I've just tried again with build 2000100520 and the same problem occurs. I think 
it is to do with the quality of the internet connection. (Try it on a dialup?)
If I open each image in the sequence first manually to force it into the cache, 
some of the images are already in the cache as half black frames. I hit reload 
and the image loads correctly. Once all the images are in the cache, the script 
runs fine.

maybe we're cacheing bad images and then using those.

, are you still seeing this with current builds? I still cannot reproduce it.

I have just tried again with M18 and it worked fine. I will try it again when 
our connection is running a bit slower, but for now, it seems OK.
