18759 - Background property of TD tag

Status: VERIFIED DUPLICATE of bug 16100

(Core :: Layout: Tables, defect, P3)

Description

[Andrei Popov]

Steps to Reproduce:
1) Go to URL specified (http://www.valinux.com/) 2) See how page renders, pay
attention to the black frame going around main topics (between 'Welcome to' and
'VA Linux Systems', and then down on the left side) Actual Results:
The frame is not black: it is messy. All sorts of collors intertwine, different
at every rendering. Expected Results:
 A straight black line of 4 or so pixels width. Build Date &Platform Bug Found:
SeaMonkey nightlies 19991107
Platform: Debian GNU/Linux, kernel 2.2.12 Additional Builds and Platforms Tested
On:
SeaMonkey builds 19991109, 19991110, 19991111 Additional Information:
This seems to be a problem with TD background property, as this is the part that
gets messed up. Site uses GIF images that get stretched to the required size by
hsize attribute. This may be also inter-related with nested tables, as an
attempt to reproduce a bug on a simple table with stretched background have not
produced the same effect.

Bug also occurs in 1999-11-12-18-M11 on Windows 98 SE.

See also bug 18162 which is about TABLE background (same symptoms).

Would the problems seen on http://www.studentmagazine.com/ be related to this
problem too?

The website http://rosenkranz.cjb.net (see bug 18786) shows this problem very
well. It is still present in the latest daily build ( 1999121612 ).
The red horizontal bars on the top and bottom of this page, and the red vertical
bar on the right side exhibit this fenomenon.
Strangly enough the background beneath the bar on the right gets corrupted when
you scroll the page quickly but is rendered correct if you scroll the page
slowly (scrolling done by dragging the scrollbar). It is even possible to
corrupt small parts of the background of the red bar by varying the speed and
direction of the scrolling.

Bug also occurs with build 2000010308 on Windows NT 4.0 sp6. Marking All/All.

It is not working in 2000010409.  Communicator 4.7 renders page correctly.

Comment 10

[Andrei Popov]

No change in 20000105 either -- still a total mess.

Comment 11

[Andrei Popov]

Similar, if not as drastic behavior is seen on any page that has a "stratched"

image (whether inside a TD or not) and a background image.  May it be that the

cause of an error is BODY tag rendering (BACKGROUND property), not TD?  Note

also (seen on a slow connection well) that *without* background test case table

is rendered properly.

This is a painting/tiling bug (thanks mats for pointing out the dependence on
TD dimensions). If you hide and then reveal the mozilla window, the colors
change (see also testcases for bug #21098 or bug #22715).

valinux.com was also discussed as bug #22643 which pnunn marked as a duplicate
of bug #16100. I'm going to mark this as a duplicate of bug #16100, and add
mats testcase to that page.
