1110118 - Closing First Time Use panel or Privacy Panel from Task Manager get it stuck on the screen and block access to the homescreen

Status: VERIFIED FIXED

(Firefox OS Graveyard :: Gaia::System::Window Mgmt, defect)

Description

[Clément Lefèvre]

Opening some panels from the settings and closing them from the Task Manager can get these panels stuck on front of the screen. User is unable to close them (it's not really opened anymore) and can't interact with it.
While having this state, it is not possible anymore to have access to the Homescreen until reboot.

It looks like it open a new pane without having it in the task manager.
So when you kill the settings pane which is probably the father, you still have the son process as zombie state.


Step to reproduce :

Privacy Panel > Quided Tour > Open Task manager > Close it by moving window to the top > Phone get stuck with it on front of the screen, no way to go back to homescreen without restarting the phone.

Or

Developper > Run First Time Use > Close it with Task manager > close it by moving window to the top > Phone get stuck to the First Time use you was on until restart.

I saw it on 2.2 [1] but I am not able to repro on 2.1 [2]: You can't go to task manager if you ran the FTU from the developer menu. I am not able to test privacy panel as this app is not in 2.1. 

I don't think asking for a regression window makes sense here as the new task switcher was landed in 2.2.

[Blocking Requested - why for this release]: Regression from 2.1 that can affect the first time experience for the privacy panel.

Issue seems to be caused by patch for  Bug 1106411 - can you take a look Kevin?

Comment 4

[Kevin Grandon :kgrandon]

It appears that the system role causes this to have some weird side-effect when in the task manager.

We'll need some other solution for this seems like. For now, we'll revert bug 1106411.

This issue still reproduces on Flame 2.2.

I cant reproduce this on today's master. The bug is still resolved/fixed but Comment 5 indicates this fix couldn't be verified?

The issue seems to be fixed for Privacy Panel since it got a dedicated app and is on the Homescreen.
It still to be an issue for the "First Time Use" experience and I still can reproduce it on latest master from right now.

At the same time, I am still unsure and maybe is it unrelated, but I begin to think that when this bug is happening, the phone forgets the Wi-Fi it is currently connected to.
I strongly suspect it, maybe can I check to be sure, but if some of you notice it too…

Comment 8

[Yeojin Chung [:YeojinC]]

I think this bug is fixed, and the behavior with FTE is a separate issue. On Flame 2.1, the user is not able to bring the card view during FTE at all, which seems to be the correct behavior.

Please see the issue on bug 1113332.

The First Time Use app does not show up in the task manager (it has role of 'system' so is excluded.) I think we're done here and can handle any FTU follow-up in bug 1113332

Closing the bug as verified.
