Hi Derek -

Do you have any update on this issue?

Thanks

The canvas coordinate system is not being updated to match the CSS-styled layout. Currently this resize update method is run on the initial "load" event as well as "orientationchange" and "resize" events. Is there another corresponding window event on Firefox OS that I can listen for when a device is unlocked? If so, I can tie this in as well.

If not, I suppose I should check this inside the ongoing game loop? I try to keep checks like this tied to appropriate events outside of the game loop, but I can incorporate a check every step if this is the only way.

Can somebody explain what are you discussing about, and why this is related to LockScreen?
The attachment is also without any information like extended file name to open it.
I don't even know what you need according to the comment 3.

Hi Greg,

Basically, is there a window event for which I can listen to know when the screen has been unlocked? Currently Entanglement handles viewport changes on the "orientationchange" and "resize" window events, but neither of these are triggered when the screen unlocks, so I'm just curious whether there is a window event triggered at this time? Thanks!

You can only listen it in System app (the 'unlock' event), so I don't think it's possible. However, I think the 'visibilitychanged' event may satisfy your request. Because that the event would be triggered when the app become a background app, and this should be a default behavior, although we recently have found a regression about it.

[Derek Detweiler]

Thanks Greg, I'll use 'visibilitychange' - it sounds like it should work for what we need.

Dear Derek,

Any update on this issue?

Not yet - I've been on vacation. I'll keep you posted.

Comment 13

[Derek Detweiler]

I've posted an updated build to the marketplace to see if the proposed solution resolves this issue.

[Lingling Zhao]

It is still not ok.

[Michael Ellis]

@Lingling Zhao- Was this issue using Firefox OS version 2.0? Is this issue still occurring on your end?  If not, I will close the bug.

Comment 16

[Michael Ellis]

I was able to reproduce this issue on Flame running 2.0.

@Derek- Are there any updates regarding the status of this bug and a potential fix date?

Comment 17

[Derek Detweiler]

There are no updates. I was unable to replicate this issue in the earlier simulators and the one potential avenue didn't work. I can try the 2.0 simulator and see if it happens to occur there. Out of curiosity, is it possible yet to get test devices in the USA?

Comment 18

[Derek Detweiler]

I just tried 2.0 Simulator, but I'm not sure how to lock the screen on the simulator in order to reproduce the problem.

Comment 19

[Michael Ellis]

Derek, I can help with your request, please expect an email at your Bugzilla email address from either Silvio or me to get the process started for shipping you a Flame reference device.

[Derek Detweiler]

The issue comes down to the game not rendering very quickly on a resize event (which seems to happen when the unlock screen pops up). So there's a sec delay between the initial CSS adjusting to when the canvas redraw is complete. Since the game is set to maintain a landscape orientation per the manifest, I removed the unnecessary resize event listener and it appears to behave better now.

I submitted an updated version to the marketplace for review.

[Michael Ellis]

Thanks for the update on this Bug Derek.  I will keep an eye out and test for the fix in the coming few days.

Comment 22

[Michael Ellis]

@ Derek- This issue is now resolved.  The update seems to have worked, thanks Derek!
