Camera.ScrollX affecting pointer coordinates / Phaser.Geom.Line?

Phaser 3
1

When the whole scene is visible, the Phaser.Geom.Line is being drawn properly.
When the camera only “sees” part of the scene, the Phaser.Geom.Line is being drawn at an unexpected position.

I want to understand where does the difference come from?

EDIT: if i use dragX and dragY for the start / end positions of the line the results are even weirder.

EDIT 2: I fixed it by adding this.camera.scrollX to the line coordinates.
