944754 - Possible to get homescreen grid into a state where tapping icons does nothing

Status: RESOLVED DUPLICATE of bug 943317

(Firefox OS Graveyard :: Gaia::Homescreen, defect)

Description

[Ben Francis [:benfrancis]]

STR:
* Open an app which takes a long time to load (e.g. Marketplace)
* Quickly hit the home button while the app icon is displayed on the full screen before the app itself is rendered.

Expected:
* Return to home, app icons work

Actual:
* Returns to homescreen
* After about a second the homescreen launching animation is displayed (though the homescreen is already on the screen)
* Touching app icons does nothing

Reproduced on a Keon with a recent 1.2 build from Geeksphone. Nominating for koi+ in case it is reproduceable on production devices.

The user workaround is to launch the task switcher, enter an open app and then return to the homescreen, at which point the icons can be used again.

Not sure if the bug is in the homescreen or the window manager.
