220848 - two background-images displayed instead of one

Status: RESOLVED FIXED

(Core :: Layout, defect)

Description

[Shark Daddy (Jonathan L.)]

This is a new bug as of some landing this week. At the URL provided, the 'WR'
background-image that goes behind the body text (defined via stylesheet) is
displayed twice, one of which being in the correct spot, the second being offset
up and left. Needless to say, the image is meant only to be displayed once, in
the center of the screen, but it is now broken in recent builds.

What exact build are you using?  I can't see, to reproduce this with a Sept 28
evening Linux build....

Does changing #contentbox to "overflow: -moz-hidden-unscrollable" change anything?

It's an evening 29th Win2k build however I noticed this on a build from earlier
in the week as well.

Indeed, the proprietary moz rule causes it to lay out as expected.

Sounds like a regression from bug 

Comment 4

[Boris Zbarsky [:bzbarsky]]

.. from bug 69355

Isn't there an existing bug on backgrounds of elements with overflow:scroll or
auto that roc's working on?  Is this the same thing?

Comment 6

[Shark Daddy (Jonathan L.)]

Err... I'll change the site back so the problem is there. I applied the -moz
rule and forgot it was on.

Yeah, looks like bug 165149, basically.

Looks fixed to me since late last year, probably by the checkin for bug 165149.
Please reopen if you can reproduce.
