759285 - document.open() content rewriting results in blurry rendering >2 screens down

Status: RESOLVED DUPLICATE of bug 747883

(Firefox for Android Graveyard :: General, defect)

Description

[Roman Rudenko]

Attachment: docwrite_blur.html

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_4) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.52 Safari/536.5

Steps to reproduce:

Loaded attached "docwrite_blur.html" testcase into Firefox Beta 12.0 and Aurora 14.0a2 (2012-05-28) on Samsung Galaxy Nexus with Android 4.0.2.
Scrolled down until "line 49".


Actual results:

Starting from very bottom of line 48, test is blurry and blotchy.
The point of breakage appears to be a fixed number of pixels away from the top
(so font size increases allow fewer readable lines).
Testing on more complex testcases shows that images and other elements are affected as well.


Expected results:

Proper text rendering.

Other notes: this bug blocks support of Fennec by Mobify-based mobile websites, as Mobify heavily relies on replacing an existing document via document.open().

Likely a dupe of bug 747883.

Looks like bug 747883 has a fix that has landed on mozilla-central and is now on Nightly. Roman, can you re-test using the latest Nightly (http://nightly.mozilla.org). If such is the case that this issue is non-reproducible anymore, we should dupe this bug over to bug 747883.
