806508 - Wallpaper-picker doesn't render any images (or even the "x" exit button) until you scroll

Status: VERIFIED WORKSFORME

(Firefox OS Graveyard :: General, defect)

Description

[Daniel Holbert [:dholbert]]

STR:
 1. Long-press an empty space on the desktop
 2. Click "Wallpaper", and *don't touch the phone*

ACTUAL RESULTS:
 The wallpaper-picker app comes up, but..
  (a) Its upper-left "x" close-button doesn't render or function. (If I tap that part of the screen, it glows blue, registering a button-press, but it doesn't back out of the app)
  (b) The visible wallpaper options are blank.

If I scroll a bit so that the "Select Wallpaper" title-bar moves off-screen, *then* the wallpapers render, and the "X" button renders as well when I scroll the title-bar back on-screen.

I'm testing using the b2g build from late last week. (dated 2012-10-24 11:07:05)

Forgot to mention -- the "X" button works, too, after I've gotten it to render by scrolling.

I can reproduce that. The problem here is that the load event doesn't fire until all the images have loaded. Until then, no buttons and/or actions work.

OK, so that's what's going on with the button.  (I don't think that explains why the images themselves don't render until I start scrolling, though.)

We believe this is a platform bug, if it still occurs for testers (triage wasn't able to repro).

I can't reproduce this with the 2012-10-31 update.  I see some flickering with paint flashing turned on but within a second or two the images render.  Please reopen if you can reproduce.

Verified WFM now -- the wallpapers and the "x" button still don't initially render, but now they show up after a second or two.

I'm using the stable dogfood build w/ datestamp 2012-11-06 20:52:24
