Closing - please follow the bug report guidelines and attach a .capx.

Why would you need a specific .capx for such a bug here? :(

This is a real bug, only on Firefox. Juste make any app and launch on Firefox. Easy to replicate...

Ok here is a capx, if really needed...

App disappears

It does stop rendering, but if you add an event that solves it.

... so not really a bug.

You mean, if there is nothing happen, it's normal that the app simply disappear ? That sounds but a bit strange. In Chrome the app doesn't disappear.

Well do you see some circumstance where the user would publish without any events?

The problem occurs even if there are some events, see the example updated. And yes, there are many examples where the game renders nothing more and simply waits for a response of the user.

So again, I don't think it's normal that an app arbitrary disappears...

Ok it stops rendering with the every x seconds event.

I guess that's because there's nothing to draw.

So I stand corrected, it is a bug.

You're right, that's because there's nothing to draw.

I tried adding a moving sprite and setting it invisible, the app non longer disappears. But it's an ugly trick.

Glad to see I'm not the only one, I'm not insane ! <img src="smileys/smiley36.gif" border="0" align="middle" />

I've noticed that too, and apparently it's indeed specific to FireFox.

Putting some sprite out of the layout with a sine behavior for example does the trick and make it so that the rendering doesn't disappear anymore.Having a sprite with an animation of several frames does the trick too.

If your project is only composed of a text object, the rendering works as intended.

From the moment you add a one frame sprite to it, the rendering will eventually disappear after a few seconds.

This issue is specific to Firefox. You should report it to Mozilla.

Actually scratch that, I found it reproduced with one of our old demos and posted a bug for it here: https://bugzilla.mozilla.org/show_bug.cgi?id=901574

Definitely a Firefox bug by the looks of things.
