Jump when going from positive to negative values

[SteveEdson]

Example video: https://www.youtube.com/watch?v=RgIh_aHAp4Q&feature=youtu.be

When tilting the phone beyond the vertical point, the scene jumps to an extreme and the edges of the layers are visible. Happening on all devices, Android phones, iPad, iPhone X etc.

Thank you for taking the time to record this video and file this issue :) I'm unfortunately really short on time right now, but will try to find at least some kind of solution for this in the future. Still have to do more testing, since the values tend to behave differently from device to device and I'm not yet sure how we could calibrate for this.

As always, any helpful ideas or suggestions are highly encouraged!

It has been a problem to me as well. However the bug is still exists but with the limit(x, y) method you can prevent the jump.

var parallaxInstance = new Parallax;
parallaxInstance.limit(20, 20);

I reproduce this bag.
Trick with limit doesn't work for me.
