285421 - Vertical scroll bar appears late in page draw, so that page appears to jump quickly to right and then left when going between 2 pages on site.

Status: RESOLVED DUPLICATE of bug 72540

(Firefox :: General, defect)

Description

[zllrwgnr]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050308 Firefox/1.0+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050308 Firefox/1.0+

Moving between the home page http://tst.ferrito.com/ and the "services" page
http://tst.ferrito.com/services/, there is a difference in the way the page
draws. For the services page, the vertical scroll bar doesn't get drawn until
after most of the rest of the page is drawn. This makes the page appear to jump
to the right and then back to the left.

This can also be seen by going to
http://tst.ferrito.com/services/firefoxBugExample.html and clicking on the "go"
button next to the address field. (In fact, after a few days, the other pages
may be different, but I will leave this one "broken".) 

The pages validate with the W3.org for the css and html as xhtml 1.0 strict.

I have removed elements from the page to see if any element was offending
Firefox. The main thing seemed to be the length of the page. None of the content
made a difference. (I swapped it with a "good" page.) The problem seems to appar
when the text goes down far enough on the browser. Nonetheless, this did not
happen with other long pages in the same site, using the same template.

And I think I know why.

There is one other factor. If the description metatag is removed or the content
element of that tag reduced in size (amount of text), the problem also goes
away, even with a long page of text.

In another page, simply reducing the amount of text in both the description and
keywords metatags fixed the problem. Reducing the size of the description alone
wasn't enough.

The latest build of Firefox (03/08/05) didn't correct this. This does not appear
in the latest build of Mozilla (03/08/05), or recent versions of IE, Opera, or
Netscape.



Reproducible: Always

Steps to Reproduce:
1. go to http://tst.ferrito.com/services/firefoxBugExample.html
2. click on the go button next to the address field
3.

Actual Results:  
The page content moves to the right as the content appears without the vertical
scrollbar, then the vertical scrollbar appears and the content jumps back to the
left. 

Expected Results:  
The scrollbar should appear earlier in the page draw so the content appears to
be visually stable.

The original problem page: http://tst.ferrito.com/services/
may be changed, but I'll leave this one on the site while you're testing:
http://tst.ferrito.com/services/firefoxBugExample.html

The page does use PHP, but I've seen the same effect on other non-PHP pages.

Thanks! I've enjoy using the browser, so I hope this helps make it even better.
