609315 - Strip of graphical corruption at bottom of tab-thumbnail, for blank / near-blank pages

Status: RESOLVED WONTFIX

(Firefox for Android Graveyard :: General, defect)

Description

[Daniel Holbert [:dholbert]]

Attachment: screenshot showing corruption

STEPS TO REPRODUCE:
 1. Load URL (an encoding of a blank HTML page) or any few-line HTML/text doc
 2. Drag page right, to expose tab strip on left

ACTUAL RESULTS: At the bottom of the tab snapshot, there's a dark bar of graphical corruption (sometimes all-black, sometimes having random colored pixels intermixed)

See attached screenshot.

I'm using latest fennec nightly installed from
http://ftp.mozilla.org/pub/mozilla.org/mobile/repos/trunk_en-US/trunk_en-US_nightly.install

While
 data:text/html,
works just fine as a testcase, here's a plain-text example with a line of content, just for the sake of having an attached testcase.

I can't reproduce on the most recent desktop Linux fennec nightly, though.

The issue doesn't seem to occur on the linux desktop of fennec, the area is black on the windows and maemo platform (Mozilla/5.0 (Android; Linux armv71; rv2.0b8pre) Gecko/20101108 Firefox/4.0b8pre Fennec/4.0b3pre).  Nightly not available on Mac

Still occurs on Android devices:

After running the Zippity SunSpider and V8 tests in landscape on an HTC Evo running HTC's Android 2.2, their tab thumbnails had similar corruptions.  The corruption vanished if I reloaded the pages.  Other test thumbnails were fine.

Also on same HTC Evo running HTC's Android 2.2 trunk ''Mozilla/5.0 (Android; Linux armv7l; rv:2.0b13pre) Gecko/20110318 Firefox/4.0b13pre Fennec/4.0b6pre', I triggered corruption at the bottom of some of the remaining thumbnails when I rapidly pressed the X in a red circle of a bunch of thumbnails.
