matrix3d, transition and borderRadius conflict on Chrome

[TommyDee]

Hi,

I'm having some problems using matrix3d and borderRadius. You can fine a fiddle here:

 

http://jsfiddle.net/wasabit/KvDEr/

 

If you run the fiddle on Chrome, the borderRadius animation isn't rendered (if you resize the browser window, the borderRadius become correct).

> if you comment "left:300" in the tweenmax call, the borderRadius animation works

> if you comment -webkit-transform:matrix3d..., the borderRadius animation works

 

I know this is not the perfect example (the original script is more complex), but I tried to make it understandable.

 

 

Hope someone can help.

Kind regards

Hi,
 
According to my minimal knowledge in 3d transform matrix, the value you're modifying (0.01) in the matrix is the perspective projection in the Z axis, but your element is not inside one that has a perspective, therefore that value won't have an effect if any because is too small.
 
A possibility would be to, instead doing it through the css you could do it through the engine, avoiding the vendor prefixes, like this:

TweenMax.set($("#container"), {z:10});

 
I updated your fiddle but the problem remains, only in Chrome, works fine in firefox, IE9+, Safari 5, which led me to think that's basically a browser issue and not the engine. Unfortunately Chrome has some issues with animations, if you google for chrome and animation issues you're going to find that chrome has problems with CSS3 transitions, jquery animate(), other js libraries, canvas and svg animations.

 

 

Here's the updated fiddle:

Another update on the fiddle in order to pass the values directly through JQuery's css method on a tween update didn't work either, you can see it here:

http://jsfiddle.net/KvDEr/3/

 

What does work is to create an independent tween for the radius with a delay of 1 second:

TweenMax.to($("#container"), 1, {borderRadius:'100px', delay:1});

Of course this kills the beauty of the simultaneous tweens, but gets the job done.

 

 

My thought is that this is mainly a chrome rendering issue and out of my capacities, maybe Jack or Carl could give us more light in this one.

 

Well I hope this helps a little,

Cheers,

Rodrigo.

TommyDee, sorry you are having issues, thanks for posting the fiddle.

Rodrigo, thanks for jumping in, very helpful.

 

We'll give this a deeper look and let you know if we find any additional info.

Another quick thing to note, using x instead of left does work fine

 

 

$(document).ready(function(){


TweenMax.to($("#container"), 1,
{
x:300,
borderRadius:"100px"
}
);


})

There's a bug in Chrome (not GSAP) related to borderRadius rendering.

Many many thanks!!
