142395 - Positioning fails for png background images

Status: RESOLVED WORKSFORME

(Core Graveyard :: GFX, defect)

Description

[Phil Housley]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.0rc1) Gecko/20020417
BuildID:    2002041711

If a png image is used as a background, it cannot be positioned.  Any attempt to
do so will stop any other statements (eg. attachments) in that style rule fail.

Reproducible: Always
Steps to Reproduce:
1. Create a page with a positioned png background.

For example: "background: url("back.jpg") center left repeat-x fixed;" will work
as expected, but the identical with a png will just display in the top left. 
The same is true if two %s are used instead of keywords

Marking worksforme based on the testcase attached above and some local
modifications to it (adding a tall div so that the body scrolls, and adding an
additional declaration in the same style attribute).

If you have a testcase that demonstrates the problem, please either mention the
URL in the bug comments or attach the testcase (in a simplified form,
preferably) to the bug, and reopen the bug report.

This was fixed sometime in the last 2 weeks with dcone's png-painting fixes for
Windows.

Attachment: png, transparent png and jpg tests

It seems I made half a mistake, it's not that it's a png that's important, it's
whether it has transparency.  This test works every time for me, although I
will attempt to update and see if Boris Zbarsky's comment is correct.  (Trans
png made with PS5.)

Just updated to today's build, seems shiny in 2002050508, anyone else agree?

That's the correct result yes, it failed on 1RC1, but seems all fixed now.

Damnit, this is back broken again on RC3.

Using build 2002052913 (SVG+MathML) on Windows 98SE, I too see a problem with
PNGs in background with transparency. (Brought it up on chatzilla a few weeks
ago, but was using an old build and was told some PNG bugs had recently been
fixed.) If I use a PNG with transparency, like
<http://www.geckonnection.com/wed2/images/binocle2.png>,
as a background image, when I cause a menu to drop down the part redrawn after
the menu goes away is redrawn positioned incorrectly. This sounds like <Bug
36694> comment #58, which was supposedly fixed long ago.

Also, a menu dropping down over a transparent PNG with the problem in <Bug
146202> causes the redrawn transparent part to be black.

This was all fixed on the trunk.  I just recently fixed in some positioning 
fixes on the branch.. June 10 build for the branch should include these fixes.

In the 2002-07-16-08 1.0.0 Branch , this works for me. Tested under Windows ME.
