Sounds like another manifestation of bug 1212257... Need a Settings dev to take a look at this. May be a System issue.

The build used to test is 20151008233852 ie 10/08/2015

Testing with today's build, I can't reproduce this issue.
Can you retry on the latest build please?

The screen isn't refreshing, having said that, if you tap the icons are there.  I think it's something with the switch to the new homescreen that doesn't have the refresh in it?  Chris, can you take a look?

Going on this, sounds like a system bug. Maybe triggered by the foreground app being a web activity handler?

n?etienne to see who'd best handle this. I could take a look, but I don't really know this part of system (and I have other bugs I need to get to as well).

Are we sure it is not just bug 1211266 ?

No, this is the entire app being missing - I'm guessing there's a missing setVisible call somewhere in system, or some kind of race-condition/conflict when switching the home-screen in this way, perhaps.

Yep, definitely something wrong on the WindowManager side.
Only reproducible when changing homescreen from the legacy one which opens an inline activity do to it.
