Setting -webkit-perspective blur ipad3 screen

Setting the CSS perspective webkit property on iPad3 makes the children very blurry, such as rendering images if they are designed to display no retina. To be clear, I'm not saying that the images are blurry and the children of the DOM are blurry.

What can be done about this?

Just deleting a property is not a parameter, since I use animations that require movement in the Z-axis.

The property is set in CSS:

-webkit-perpective: 500;

Thanks for any help with this!
