Use a normalization of the transform after your animation:
Transform X/Y normalization
Or We scale the texture with zoom double, then scale down again. In some cases this cannot be applied due to other complex transformations or translations, and is not perfect.
...{
zoom:2;
-webkit-transform: scale(0.5);
transform: scale(0.5);
}
