Parts of the page are rendered on top of each other. This won't occur the first time the page is rendered but will occur when the page is reloaded.

I see this also with Linux build 2001052308, even on the first load. Changing OS to all.

Correction: the first time I loaded it I saw the problem, when I reloaded it the problem was still there. However going to another page, then coming back, it gets rendered correctly. If you then hit reload it looks messed up. So it seems to be the only time it looks OK is a fresh reload from cache.

Confirming on 2001052608 Win2k, upping severity to Normal, and over to HTML Tables as the layout is made with a table. I'm seeing similar problems on http://www.firaxis.com/features/e3_2k1/ and https://www.1822direkt.com/onlineb.ns4.html, but I don't know if those belong to the same bug. I remember having seen a similar bug report before, but I don't know the bug number.

Updating summay from "Slightly odd rendering of layout" to "Page elements display on top of each other".

Amar, can you please develop a test case.

I've tried to make a local testcase but couldn't. The bug seems to be caused from the reflowing of the table after loading the logo http://www.oasis-open.org/cover/images/rclogo460.gif

Removing Status Whiteboard & Keywords. If you can find it good but I cant.

Well, I just spent 30 minutes adding a comment to this bug, only to have it wiped out because bugzilla wouldn't accept "correctness" and "nsCatFood" added by me, and the comment was gone when I hit the back button as recommended. If you don't want to trust the help you get from your users, I guess you'll have to live with less help.

Build 2001061520 win32 installer sea talkback trunk I can only see the effect of the bug in the last two testcases I attached when: 1. the browser window is maximised 2. pressing reload after opening the testcase

Another test case bottom of the science pages in the nytimes, (free subscription site) This is an example one: http://www.nytimes.com/2001/06/24/national/24PIPE.html

pg can you create a simplified testcase out of that page?

Open the attachment and then hit reload and you should see overlaping images.

Any relations with bug 83769??

Think this bug doesn't owe the awareness it should. This one is having quite a great impact on mozilla and there are a few around describing the same problem. We should try to get this one down real soon.

Working with the testcases, I was able to pin this down to a problem with the image element, not the table (although something screwy is still happening with the table layout). If you add an explicit height and width to the image 'rclol460.gif' then the overlap does not occur. It would seem that an 'auto'-sized image is ignored for the purposes of progressive table layout on the first pass. In some circumstances this can cause table cells to overlap other table cells, dragging their content along with them. Resizing the page will fix the problem as the cell "magically" jumps back to its proper spot, with the content again going along for the ride. (Getting a reload straight from cache also avoids the problem for some reason.) http://bugzilla.mozilla.org/showattachment.cgi?attach_id=38770 demonstrates this problem best, I think, especially since it demonstrates that explicitly-sized elements are not affected by this odd behavior. I will be attaching some testcases (modifications of the first two attachments) to this entry in a few minutes and hope that the information presented will allow the Mozilla folks to fix this one in a jiffy. I've seen it in a few sites (zoomerang.com for example) and fixing this would be a major win.

Well, my testcase (http://bugzilla.mozilla.org/show_bug.cgi?id=87418), which is supposed to be the same problem as this, can't be fixed by specifying any image size, because the image is the background of a table. http://overosa.dhs.org/musik.html

I didn't mean to imply that the sole source of trouble was the image not having height and width-- just that adding them "resolved" the layout problem, which would hopefully lead the coders to the right place in the table layout code to actually fix this. With luck, that will also resolve the problems reported in #87418.

Oki, I see. Sorry :)

testcases from bug 90482 http://www.world-direct.com/mozilla-table-bug-testcase/index2.html http://www.world-direct.com/mozilla-table-bug-testcase/ can someone verify that bug 90482 is a dup of this bug?

testcase from 87418 http://overosa.dhs.org/musik.html

attachment 38770 [details] looked good when I visit it for the first time but looked messy second time and now it looks messy always. same with http://www.nytimes.com/2001/06/24/national/24PIPE.html, when I visit it for the first time I see it good but now and ever it's messed up (the bottom). I have "Enable Mem Cache" [x] turned on and "Enable Disk Cache" [ ] turned off. what about http://www.zdnet.com/ ? it's also messy ... there are some <hr> elements overlapping the text and pictures through http://pes.internet.cz/ page.

Another testcase: https://ibp.scandinavian.net/secure/booking/pleasure/psearchavailability1.asp?Youth=1 The text overlaps the image. Notice that if you type something into the "Leaving From" field, then minimize the window and maximize it again the page will display correctly again. Shift-reloding it later brings back the overlap. This page looks fine in 4.x.

I didn't have much time to investigate properly (sorry), but I think that following URL is demonstration of this bug, too. http://areyours.com/s/inmigracion/programas/jubilarse/index.html I know that page has lot's of errors and is not valid HTML, but it is rendered fine in K-meleon 0.4, which uses Gecko (version from moz 0.9.1 IIRC) so the problem is IMHO somewhere in latest mozilla. --mondo

The patch is in.

This fixed most problems I saw (zdnet.com, netem.cz) but I still see some overlaping (<hr>/<img>/text elements) on http://pes.internet.cz/.

amar or martin, can you file a new bug for the remaining issue on the new site. This bug has had enough.

OK, I filled bug 94320 about this http://pes.internet.cz/ mess...

I'm afraid the bug on http://overosa.dhs.org/musik.html is still occurring (aug 22 nightly): http://bugzilla.mozilla.org/show_bug.cgi?id=58653

Sorry, sorry! That was the wrong bug # The original bug is http://bugzilla.mozilla.org/show_bug.cgi?id=87418 That's the issue that is happening again. All of iesbild.com works fine in Mozilla! Again, I am sorry.

The testcase looks good even after reloading.. verified on win2k and Linux 7.1 Build ID : 2001-09-24
