Bulge adjustment layer doesn't work with position changes

Question

I'm working on a simple 'fake' globe effect using a bulge adjustment layer with the center parented to a globe composition layer's position. However, when I try to move the globe's position, the bulge does some weird warping and then settles back into place once the globe is done moving.

I have gone through and adjusted the bulge's radius animation path so that it stays within the globe layer throughout the animation. There doesn't seem to be a clear reason for why it's doing this.

I don't think the radius is the cause, as the weird warping occurs when I move the globe in position only. Please help! Thank you!

Edit: Did some tests and I think it has something to do with how the bulge works when out-of-frame. Editing the position or scale of the globe when it's in-frame looks perfect. Exactly how I want it to look. It's only when I animate the globe going out-of-frame or into-frame that it has that weird effect. I don't even know if this is fixable now.

Try to turn off Pinning.

It might be a problem with the horizontal and vertical radius of the bulge effect.

You should use an expression to calculate it dynamically based on the scale of the Globe layer.

Try this expression on the horizontal and vertical radius properties of the bulge effect:

scaleFactor = thisComp.layer("Globe").transform.scale[0] / 100;
value * scaleFactor
