Status: RESOLVED FIXED

(Core :: Web Painting, defect)

Description

[Christian]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040616

This page was looking perfectly right up to mozilla 1.6 final but from 1.7 
alpha and in Firefox 0.9/0.9.2 started to do this strange thing; it happens 
the same with a windows media player window. It does work fine in Netscape 7.1.
The problem appear only if you put the iframe (or the media player window) 
inside a floating div (3 columns floating div layout).

Reproducible: Always
Steps to Reproduce:
1.just go to the page and see it.
2.
3.

Actual Results:  
The iframe flashed badly on the screen.

Expected Results:  
Shouldn't flash.

I am a web developer and I always try to make my pages work at least in 
Mozilla/Firefox/Opera/IE but this bug really bother me a lot because a lot of 
my sites use the same system and they all do have the same problem.
Please try to fix it asap because I really like your browsers and I would like 
my clients to have a nice experience on my sites with them.

Attachment: reduced example

It appears to be related to the scrolling script you're using. I've reduced the
html and css here, hope it helps a bit.

This looks like a similar situation as in bug 250416.
I haven't investigated it, but this could also be related to bug 132337 and bug
246138.

If you set the iframe style position as absolute it will work perfectly fine :)

Sounds like a dup of the "we need caching of widget changes" bug....

-go to http://hardware.no/ (and get dizzy.. whole page flickers badly these days)
-scroll two pages down till you see a small add in an iframe, middle of page
-click a "story-link" above or below it (while you still see the add)

result: as you click, the gif in the add brifly appears another place on the
page, in addition to its usual location
