539286 - Lots of checkerboarding on zoom out after panning

Status: RESOLVED FIXED

(Firefox for Android Graveyard :: Panning/Zooming, defect)

Description

[Aakash Desai [:aakashd]]

Build Id:
Mozilla/5.0 (X11; U; Linux armv7l; Nokia N900; en-US; rv:1.9.2pre) Gecko/20100112 Firefox/3.6pre Fennec/1.1a1pre

Steps to Reproduce:
1. Go to www.slashdot.org
2. After page is loaded, pan down to the bottom of the page
3. Wait for the tiles to paint and double tap on the "comments" text at the bottom of the last entry
4. Double tap to zoom out

Actual Results:
Most of the page is checkerboard-ed except for the previously zoomed-in portion of the page

Expected Results:
Since the tiles were already painted before zooming-in, I would expect those tiles to still be painted rather than having to re-paint them.

The same thing can be seen while zooming in/out on the flash snippets on www.fandango.com
