Errata Type: Code | Page 33 ad 34

For the properties _ScrollXSpeed and _ScrollYSpeed, Assume they are in units per second, but when we calculate the xScrollValue and the yScrollValue, we multiply them by _Time (Or _Time.x).

In Unity's docs however, _Time.x = t/20, while _Time.y = t.
To have a correct speed per second, we should write :
fixed xScrollValue = _ScrollXSpeed * _Time.y;
fixed yScrollValue = _ScrollYSpeed * _Time.y;
