Label node following mouse

Question

I have a Label node that shows some information and the label position should follow the mouse with offset. I put this simple code. Label follows the mouse (with offset), but if I move mouse quickly, the label follows the mouse with a delay, as if I used a lerp.

It’s not necessarily undesired for my use-case, but I’d like to understand why it’s happening.

extends Label

var offset : Vector2 = Vector2(30,45)

func _process(delta: float) -> void:
	position = get_global_mouse_position() + offset

That’s unfortunately the problem you can’t really solve. See here a similar topic with a thorough explanation.

Fix Mouse Position Lag

This is inherent to how the OS mouse cursor is drawn compared to any other window, and is not an issue exclusive to Godot. You can’t fix this entirely unless you replace the mouse cursor image with the sprite’s texture, which you can do using OS.set_custom_mouse_cursor(). The arrow will still appear to lag behind slightly though, which you could mitigate by making look_at() point towards the extrapolated (predicted) mouse cursor’s position instead of its current mouse position. Doing so will int…
