App disappearring on Firefox

  • Steps to reproduce:

    1. Create new project

    2. Add a textbox and a button

    Expected result:

    No disappearing.

    Browsers affected:

    Chrome: no

    Firefox: yes - Everything is up-to-date, tested with no addons.

    Internet Explorer: no

    Operating system & service pack:

    Windows 7 Home, last update

    Construct 2 version:

    Release 132 (64-bit)

  • 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...

  • Try Construct 3

    Develop games in your browser. Powerful, performant & highly capable.

  • 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.
