499308 - on Fx3.5 black borders surround background images in zooming out, regression since Fx3

Status: RESOLVED DUPLICATE of bug 468496

(Core :: Layout: Block and Inline, defect)

Description

[Pascal Chevrel:pascalc (PTO until April 26)]

Attachment: screeshot of the border artefacts

Mozilla/5.0 (X11; U; Linux i686; fr; rv:1.9.1) Gecko/20090615 Firefox/3.5

If you zoom out on https://et.www-trunk.stage.mozilla.com/et/ (ldap required) with CTRL- you will see black borders appearing around some of the background images.

This is a regression, works fine in Firefox 3 (and Opera/webkit).

Attaching screenshot

If I take a screenshot with an external tool, the missing borders are captured, but if I take the screenshot from The Page Saver addon based on canvas, the resulting saved image is correct.

Just tried in Vista in a VM and it doesn't have the bug.

bug 477552 is now marked a duplicate of bug 468496 and apparently that's not a transitive property.
