631481 - Screen is half gray on about:firefox and about:firstrun, when going back from another "about" page

Status: RESOLVED WORKSFORME

(Firefox for Android Graveyard :: General, defect, P2)

Description

[Andreea Pod]

Attachment: half gray screen

Mozilla /5.0 (Android;Linux armv7l;rv:2.0b12pre) Gecko/20110203 Firefox/4.0b12pre Fennec /4.0b5pre 
Device: Samsung Galaxy S Captivate
OS: Android 2.1 update 1

When pressing back from a system page the previous page is gray at the bottom. I see this only if the previous page was about:firefox or about:firstrun.

Steps to reproduce:
1. Go to about:firefox
2. Go to about:firstrun or about:config
2. Press back button 

Expected results:
The pages should appear with no problem

Actual results:
The bottom half of the page is gray (please see the screenshot).

Confirming. This only happens to me when I do this in fennec's *first* tab. (which normally starts out showing a "Fennec Start" header, tabs from last time, and recommended addons)

In that tab, if I visit about:firstrun and then about:firefox and then I hit "back", I see a half-gray page, like in the screenshot.

I'm using Nexus S with latest mozilla-central fennec nightly.  (20110424)

If I switch my input method to use a bluetooth keyboard instead of Android Keyboard, the bug seems to go away, so I think this stems from needing to repaint the area under the android keyboard.
