Deyan Vitanov commented on CB-11110:
------------------------------------
I've found the problem. It has to do with hiding and showing the inputs on a
tabs panel.
In our implementation we put "class" objects (which contain the input) in array
and hide/show them using style.display and input.visible.
It was a bad idea to make mix of canvas UI and html input on top.
Anyway here is some code that makes the cordova freeze:
window.TextInputInstances = [];
var TextInput = function(type) {
PIXI.Container.call(this);
this.bg = this.addChild(new PIXI.Graphics());
this.domElement = document.createElement('input');
this.domElement.type = type;
this.domElement.className = 'gameTextInput';
this.domElement.style.fontSize = (42 * config.gameScale) + 'px';
this.visible = !!this.visible; // update dom element's
style.display property
document.getElementById('gameContainer').appendChild(this.domElement);
window.TextInputInstances.push(this);
};
TextInput.prototype = Object.create(PIXI.Container.prototype);
TextInput.hide = function() {
TextInput._hidden = true;
TextInputInstances.forEach(function(inst) {
inst.domElement.style.display = 'none';
});
};
TextInput.restore = function() {
TextInput._hidden = false;
TextInputInstances.forEach(function(inst) {
inst.visible = !!inst.visible;
});
};

> I have a Cordova app that works great on Android and iOS, but the same code
> on windows phone 8 and 1 has this issue.
> When I touch the input - the keyboard appears and I can enter text.
> But when I click outside the input (the game canvas) - the game freezes.
> All buttons become unclickable and there is nothing in the console.
> I can only drag the webview - but nothing more. The keyboard does not go
> away..the input is freezed..no errors.
> I tried with cordova 6.0.1 ro 5.1.1 - no difference (bug is present)
> It freezes on phones and emulators.
