Touch Event Bug

  • Link to .capx file (required!):

    dl.dropbox.com/u/30381754/Touch%20Test%20Application.capx

    Steps to reproduce:

    1. Run project in Google Chrome App on laptop with touch screen (mine is an Asus SonicMaster N6 series)

    2. Touch the screen, usually with quick taps.

    Observed result:

    Touch count increases by one for each touch, but some do not decrease.

    When the screen is single touched, a black circle appears in at the position of the initial touch, but sometimes doesn't disappear after the touch has ended.

    This can lead to touch count values like these:

    <img src="https://dl.dropbox.com/u/30381754/Touch%20Issue%20screenshot%20%28800x524%29.jpg" border="0" />

    These issues appear more likely to occur with quick taps of the screen, as long held touches do not appear to have effect.

    Expected result:

    Touch count increases by one at start of touch, and decreases by one the end of a touch.

    When the screen is single touched, a black circle appears in at the position of the initial touch, and disappears when the touch has ended.

    Browsers affected:

    Chrome: yes

    Firefox: no

    Internet Explorer: no

    Operating system & service pack: Windows 8 64-bit Pro

  • Can you make a simpler .capx? As it is the events are complicated enough that it's not obvious this is not just a mistake in your events.

    Edit: also, your .capx does not match your screenshot, I don't see a touch count text showing.

  • I've done a bit more testing and found that the bug does not occur while running it on Android using CocoonJS, or when exported as a Windows 8 App. Therefore this bug of mine occurs as a HTML5 Application both exported and running from the capx file.

    Sorry about that, I updated that old .capx file. I've made a simple .capx like you requested. All it does is draw text that details the amount of touches using "TouchCount". I've also changed the screenshot to demonstrate this new one. <img src="smileys/smiley1.gif" border="0" align="middle" />

  • I didn't move this, but probably because it looks like a duplicate of this. Please only report bugs once.

  • Sorry about that, I've just checked and Google appears to have fixed the bug now.
