Chrome 67 parallax bug

[psy]

Heads up for any PW developers who use parallax images on the front end of their sites. Chrome v67 has introduced a bug - grrrrr. A quick search found the solution for me:

In your CSS:

/* google chrome 67 parallax bug fix */
.parallax {
    transform: translate3d(0,0,0);
    -webkit-transform: translate3d(0,0,0);
}
