Dot filling is not constant with fixed seed

[tneullas]

Hello, I want to use dots fillStyle but I have an issue with it.
Everytime I use it, it changes dots positions even if the seed is fixed.

In my app, I have a loop to draw and dots are moving on each draw call which is quite disturbing.
Note that I have tested with others fillStyle and it works for others filling.
Here is my conf if it can helps :

{
    fillStyle: "dots",
    fill: "rgb(119, 217, 93)",
    seed: 1,
    stroke: "black",
    roughness: 3,
    strokeWidth: 5
}
