Good afternoon my friends.

I have this little character, which is a drag and drop sprite and it produces a line as it is dragged; the drawn line script is on the 2D Line node itself and works fine.
However, sometimes it stops working randomly and does not return to work anymore; could anyone help me to understand my mistake?

Thank you!

the code:

extends Line2D

var target
var point
export (NodePath) var targetPath

func _ready():
    target = get_node(targetPath)

func _process(delta):
    global_position = Vector2(0,0)
    global_rotation = 0
    point = target.global_position

I experience the same issue with Godot 3.2.1 stable mono.

When the Line2D reaches 2700 Points, funny things start to happen like in your screenshot and video.

I found the solution to this problem.

In Project Settings go to Rendering > Limits > Buffers and increase the two settings for canvas_polygon_index_buffer_size_kb and canvas_polygon_buffer_size_kb.

The default is 128, which is quite low.

PS: the TargetPath is the Sprite itself

sometimes the last point drawn before the bug returns to the 0,0 position and then stops working. but only sometimes.
I think it's related to global_position, but I'm not sure what can be done to correct.
