The current behaviour I see is:
* same STR
* we see the icon full screen that doesn't hide

I see this since the screenshot refactoring some time ago.

Naoki, do you see this on the 1.1 branch ? I only saw it on master. I see this quite often hence the koi nomination.

Trying to raise awareness on this by asking koi? and flagging Alive.

Thanks for flagging me. But I couldn't reproduce it.
What I see:
If I press home button quickly right after app is opening, the homescreen app would do close transition "two times".

Nicolas, could you please clarify what you told me you see on your device ? And if it is 1.1 or master ? Thanks !

What I saw Friday night on Michal phone, was the background of the home screen without any icon nor search bar.
This was on the phone used for the demo, so the bug was present Friday morning on master.

I was able to reproduce the same bug on a Nexus 4.  So this does not depend on the hardware/software home button.

QA, can you please test this on both 1.1 and master and report results here ?

Thanks !
