Status: RESOLVED DUPLICATE of bug 134887

(Core :: Layout, defect)

Description

[Frank Burleigh]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:0.9.9+)
Gecko/20020426
BuildID:    2002042603

This page produces all sorts of display remnants.

Reproducible: Always
Steps to Reproduce:
1. Open the page, then use pagedown to move down the page.


Actual Results:  "menu bar" remnants left on the page.

Expected Results:  Clean painting.

But if one moves down the screen with arrow keys, the painting seems cleaner,
without remnants.  Someone with more knowledge of the browser's architecture
will be better positioned to categorize this bug.

To dcone to investigate (sounds like the stuff he's been doing).

This looks good on my machine.. probably because I just fixed bug number 134887
which had some PNG 8 bit problems.. which this page has also.  I am marking this
a duplicate of that.. and this should be fixed as soon as I get the r and sr for
bug 134887.

Attachment: a new testcase

I am experiencing similar problems with firefox 2.0 and 3.0 on Linux.
I Attached a "dump" of the Planet Ubuntu page with the problem.
When I deleted more posts from the page, the problem was gone.
Note that the page is not valid xhtml as it claims to be, but I don't think it has anything to do with the bug.
