Description

Run the below code and you will see that the label position is changed properly when 'btTestAnimate' is clicked.

var win = Ti.UI.createWindow({
backgroundColor:'white',
});

var coords = Ti.UI.createLabel({ text:'coords' });

win.add(coords);

var btTranslate = Ti.UI.createButton({top:100,title:"btTranslate"});
win.add(btTranslate);

var btTestAnimate = Ti.UI.createButton({top:200,title:"btTestAnimate"});
win.add(btTestAnimate);

var t1 = Titanium.UI.create2DMatrix();
btTranslate.addEventListener("click",function(e){ t1 = t1.translate(50,0); coords.transform = t1; });

btTestAnimate.addEventListener("click",function(e){
t1 = t1.translate(50,0);
coords.animate({transform : t1,duration:1000});
});

win.open();

But if the matrix is concatenated, it doesn't use the propery animation is not used and the result is not persisted which causes the label to flicker. Run the below code to see the behaviour

var win = Ti.UI.createWindow({
    backgroundColor:'white',
});

var coords = Ti.UI.createLabel({
    text:'coords'
    });

win.add(coords);

var btTranslate = Ti.UI.createButton({top:100,title:"btTranslate"});
win.add(btTranslate);

var btTestAnimate = Ti.UI.createButton({top:200,title:"btTestAnimate"});
win.add(btTestAnimate);

var t1;
var i = 1;
btTranslate.addEventListener("click",function(e){ t1 = Titanium.UI.create2DMatrix();t1 = t1.translate(i*50,0); coords.transform = t1; i++});

btTestAnimate.addEventListener("click",function(e){
    t1 = Titanium.UI.create2DMatrix();t1 = t1.translate(i*50,0);i++;
coords.animate({transform : t1,duration:1000});
});

win.open();

[~hamzaezzi] Apologies, it is unlikely. Perhaps in a future version. If you can get more people to "watch " the ticket, that might influence how fast it is fixed.
