31513 - mozilla react very slowly

Status: VERIFIED DUPLICATE of bug 31044

(Core :: DOM: Core & HTML, defect, P3)

Description

[Christophe.long]

when going to this url http://www.webmotion.com/news/index.en.html, mozilla
takes a lot of time to display it, a line appear in the middle, and the scroll
bar react after 10 seconds. Previously on the same page a bug of displaying the
background picture was corrected ( now it is displayed quite well, except the
line )

Looking good to me (but then I have a fast link) except for some strange table 
background colour issues I will investigate later. 
                                                                           
[e-mail] - what sort of link are you using? What do you 
mean by a line in the middle? Please also could you give us the Build ID (it's 
the set of numbers in the bottom right of the browser window).

unable to connect to this URL at all.  Are you guys still able to connect to
this URL?

This URL consistently hangs the browser (20000324 W95). I'll work on a test case 
when I get around to it :-)

I was mistaken - this isn't a total crash. Mozilla hangs for about 20-30 
seconds, then starts responding again with the page loaded (albeit with some 
table bgcolor graphical glitches). Passing to Layout, because I suspect that's 
where Moz is getting confused.

Hmm. Something very strange is going on with this page. My guess (although I 
don't have any real evidence) is that it is related to the JavaScript on the 
page

[Johnny Stenback (:jst)]

Troy, no script problems here, the page contains a

	<TABLE BACKGROUND="../images/1x1-transp.gif"...

(it's a 1x1 transparent gif AFAIK) and that's what makes it slow, I think this
is a dup but I don't know who owns it but it's not me, back to you troy to
reassign to the correct person.

Thanks Johnny.

Assigning to Don Cone to look at the issue of why the 1x1 background image is so 
slow

[dcone (gone)]

Transparent GIFS are very slow.. each platform will get platform specific fixes.  
This is a duplicate..
