792638 - Scrolling on video.disney.com up and down the site from top to bottom eventually completely starts layering images, text, and banners in the incorrect order

Status: RESOLVED DUPLICATE of bug 793365

(Core :: Graphics: Layers, defect)

Description

[Jason Smith [:jsmith]]

Attachment: Z-Indexing mess on video.disney.com

Build:

* Device: Otoro
* Gaia: afb2a8ccbfce4df017d92ac1ccc5956ca8d01f83
* Mozilla Central: c03abe4968949a27e21c7496e00c9c2ab37b158f

Steps:

1. Go to video.disney.com
2. Start scrolling to the bottom of the page, then scrolling to the top a few times

Expected:

The page's content should change based on the direction you scroll, but the ordering of the content should not change on subsequent times you review the same content during the multiple scrolling sessions.

Actual:

Eventually, the ordering of the content gets shifted way out of order, resulting in images on top of text, banners being out of order, etc. See a screenshot for an example I hit on device.

Note - this is reproducible (seen it happen three times in a row so far).

Is this a regression?

Adding qawanted to see if this is a regression or not.

Jet, is this a layout issue?

Comment 4

Can anyone still reproduce this?  The comments about layering and z-indexes might have been a red herring; this might be a dup of bug 793365.

I'll retest on the 9/26 build shortly.

Can't reproduce on the 9/26 build. It does sound similar to bug 793365, so I'll dup on that.
