242230 - Ghost flashes of iframe during pageload (blinking/jumping iframe)

Status: RESOLVED DUPLICATE of bug 132337

(SeaMonkey :: General, defect)

Description

[Stig Nygaard]

User-Agent:       Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.7b) Gecko/20040421

Try to load http://politiken.dk/ and notice how (at least for me) the
"Eniro" box at top-right of the page has "ghost flashes" at top-left during load
of the page. The Eniro-box is an iframe.

I see this problem on both my Mozilla installations:
1) Mozilla 1.6 on Windows XP
2) Mozilla 1.7RC1 on Windows 98

Further down on politiken.dk there's a similar problem with another iframe
(The add-banner just above the Wulffmorgenthaler comic).

Also I noticed (at least on my Moz1.6/XP) there is the same short "ghost-flash"
when tabbing to a page where politiken.dk is loaded.

I know from a comment in bug 236598
(http://bugzilla.mozilla.org/show_bug.cgi?id=236598#c14) that the jumping iframe
can be seen on some Linux systems too (same versionnumbers as my browsers).

Reproducible: Always
Steps to Reproduce:
1. Load http://politiken.dk/
2.
3.

Seems to be a dupe of 
Bug 228059 Flickering when floating two divs, one with overflow: auto and the
other with a:hover and display:none on imgs

See also Bug 241717  Iframe (?) makes content flash on upper screen when loading

Both bugs have testcases

Sure this is a duplicate of bug 132337 ? Bug 132337 seems to be an old bug (from
2002), but I havn't noticed this problem until sometime this year I think, and
politiken.dk is not the only place I'm seeing it.
