The example shows two boxes. When you click the screen, the right box (which is initially hidden) moves to the left and transforms to opacity 1, while the left box moves to the right and transforms to opacity 0 with a slight delay (using -webkit-transition-delay). When AC is not enabled, the transforms work properly, but when it is enabled the box with the delayed animation disappears and then does not start it's transform until the other box finishes. Without the delay everything works fine with or without AC. 242326 1 noam 2010-06-23 23:48:38 -0700 This might be a duplicate of 40846 243165 2 noam 2010-06-25 13:20:21 -0700 *** This bug has been marked as a duplicate of bug 40846 *** 58997 2010-06-17 08:36:42 -0700 2010-06-17 08:36:42 -0700 Test with run-launcher -graphics-based index.html text/html 1294 kevin.simons PGh0bWw+Cgk8aGVhZD4KCQk8c3R5bGU+CgoJCQlib2R5IHsKCQkJCW1hcmdpbjogMHB4OwoJCQl9 CgoJCQlkaXYgewoJCQkJcG9zaXRpb246IGFic29sdXRlOwoJCQkJd2lkdGg6IDQwMDsKCQkJCWhl aWdodDogNDAwOwoJCQkKCQkJCS13ZWJraXQtdHJhbnNpdGlvbi1kdXJhdGlvbjogNS4wczsKCQkJ CS13ZWJraXQtdHJhbnNpdGlvbi1wcm9wZXJ0eTogLXdlYmtpdC10cmFuc2Zvcm0sIG9wYWNpdHk7 CiAgICAJCQktd2Via2l0LXRyYW5zZm9ybS1vcmlnaW46IGNlbnRlcjsKICAgIAkJCS13ZWJraXQt dHJhbnNpdGlvbi10aW1pbmctZnVuY3Rpb246IGVhc2UtaW4tb3V0OwogICAgCQkJb3BhY2l0eTog MDsKCQkJfQoKCQkJI2JveDEgewoJCQkJYmFja2dyb3VuZC1jb2xvcjogYmx1ZTsKCQkJfQoKCQkJ I2JveDIgewoJCQkJYmFja2dyb3VuZC1jb2xvcjogYmxhY2s7CgkJCX0KCgkJCWRpdi5hY3RpdmUg ewoJCQkJb3BhY2l0eTogMTsKCQkJCS13ZWJraXQtdHJhbnNmb3JtOiByb3RhdGVYKDBkZWcpIHJv dGF0ZVkoMGRlZykgc2NhbGUoMSkgdHJhbnNsYXRlWCgwJSk7CgkJCX0KCgkJCWRpdi5pbmFjdGl2 ZSB7CgkJCQlvcGFjaXR5OiAwOwoJCQkJLXdlYmtpdC10cmFuc2Zvcm06IHJvdGF0ZVgoMGRlZykg cm90YXRlWSgwZGVnKSBzY2FsZSgxKSB0cmFuc2xhdGVYKDEwJSk7CgkJCQktd2Via2l0LXRyYW5z aXRpb24tZGVsYXk6IDIuMHM7CgkJCX0KCgkJPC9zdHlsZT4KCQk8c2NyaXB0IHR5cGU9InRleHQv amF2YXNjcmlwdCI+CgkJCXZhciBhY3RpdmUgPSB0cnVlOwoJCQl2YXIgYjEsIGIyOwoKCQkJZnVu Y3Rpb24gaW5pdCgpIHsKCQkJCWIxID0gZG9jdW1lbnQuZ2V0RWxlbWVudEJ5SWQoImJveDEiKTsK CQkJCWIyID0gZG9jdW1lbnQuZ2V0RWxlbWVudEJ5SWQoImJveDIiKTsKCQkJfQoKCQkJZnVuY3Rp b24gdG9nZ2xlKCkgewoJCQkJY29uc29sZS5sb2coInllcyIpOwoJCQkJaWYoYWN0aXZlKSB7CgkJ CQkJYjEuY2xhc3NOYW1lPSJpbmFjdGl2ZSI7CgkJCQkJYjIuY2xhc3NOYW1lPSJhY3RpdmUiOwoJ CQkJfSBlbHNlIHsKCQkJCQliMS5jbGFzc05hbWU9ImFjdGl2ZSI7CgkJCQkJYjIuY2xhc3NOYW1l PSJpbmFjdGl2ZSI7CgkJCQl9CgoJCQkJYWN0aXZlID0gIWFjdGl2ZTsKCQkJfQoJCTwvc2NyaXB0 PgoJPC9oZWFkPgoKCTxib2R5IG9ubG9hZD0iaW5pdCgpOyIgb25jbGljaz0idG9nZ2xlKCk7Ij4K CQk8ZGl2IGlkPSJib3gxIiBjbGFzcz0iYWN0aXZlIj48L2Rpdj4KCQk8ZGl2IGlkPSJib3gyIiBj bGFzcz0iaW5hY3RpdmUiPjwvZGl2PgoJPC9ib2R5Pgo8L2h0bWw+Cg==
