Description: When the user is attempting to add "cc" or "bcc" contact from the contacts list after the keyboard has been invoked (typing in the subject or email body), the contacts list is displayed partially, lower half of the screen is white out Prerequisites: have contacts list available on the test device Repro Steps: 1) Updated to Leo Build ID: 20130708070214 2) Open Email app 3) Select to create a new message 4) Type in the subject line 5) Add "bcc" recipient from the contacts list ("+") 6) Scroll down the contacts list Actual: Lower part of the screen is white out, contacts list displays only at the top Expected: Contacts list opens up in full view Environmental Variables Gecko: http://hg.mozilla.org/releases/mozilla-b2g18/rev/8c0127cc7be3 Gaia: 7c40bdaeaffae708342fc773926dcfac5389348e Platform Version: 18.1 Notes: Repro frequency: 100% See attached screenshot

The contacts list is provided by the contacts app, triggered via webactivity. This seems like a contacts regression or system regression interfering with contacts.

I just tried with a recent gaia master and gaia v1-train using a mozilla-central gecko build. The problem did not reproduce in either case. I'm building a b2g18 image to see if that triggers the issue.

I was able to reproduce by flashing b2g18 gecko. It seems like there is a compositing issue or something going on. I am also getting weird flashing in settings app, scrolling the contacts list, etc.

My apologies. This does appear to be a v1-train gaia issue. I had forgotten to update my local tracking branch.

Bisecting shows that this was introduced by: https://github.com/mozilla-b2g/gaia/commit/5d7a0da528dce626b563abafc135eb828599d3c0 Rex, any thoughts on what is happening here?

Seems the newly added |appWindow.resize()| failed on calculating window size of inline activities.. Investigating.

Seems like a regression that I didn't discover in bug 877903.. I can reproduce it only in v1-train, but seems the code in master is just kind of "lucky hit" which is not using the correct way, so I'll patch both side. Alive, would you help reviewing this? Thanks a lot!
