586688 - Vertical white line appears in image after -webkit-transform: scale, disappears after redraw

Status: RESOLVED WORKSFORME

(Core :: Web Painting, defect)

Description

[Grant Heaslip]

User-Agent:       Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b3) Gecko/20100805 Firefox/4.0b3
Build Identifier: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b3) Gecko/20100805 Firefox/4.0b3

When the image on the linked page is clicked, it scales up. In Firefox 4.0b3, a 1px white line appears close to the right side of the scaled-up image (this doesn't happen in 4.0b2). The line disappears if I switch away to the back and back again, if Firebug triggers any kind of highlight effect on the page, or if I re-size the window (basically, if anything tells Firefox to redraw the window contents).

Reproducible: Always

Steps to Reproduce:
1. Click the image
Actual Results:  
A white line appears near the right side of the image after it re-draws.

Expected Results:  
The image should re-draw without any visual glitches.

I'm running OS X 10.6.4 on a 2GHz Core 2 Duo Mac Mini 3,1 with the NVIDIA GeForce 9400 graphics chipset.
