1179010 - Previous page's contents not erased behind undecoded decode-on-draw image

Status: RESOLVED FIXED

(Core :: Layout: Images, Video, and HTML Frames, defect)

Description

[Markus Stange [:mstange]]

Attachment: bad (after bug 1162064)

Steps to reproduce:
 1. Create a Firefox profile with e10s off and APZ on. (This won't get you APZ, but the pref itself is checked in a crucial place.)
 2. Go to any web page.
 3. Navigate the tab to http://imgur.com/pO2tw3U .

For a brief moment, you will see remnants of the previous page in the parts where the main image (and sometimes the header image) should be displayed.

mozregression found this range, and I confirmed it: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=b485fe97c048&tochange=a509c974aa1f

In builds before that change, the image background is white (main image) or black (header image) until the real image was displayed.

This might be fixed by bug 1178274.

Certainly fixed by bug 1183836, if nothing else.
