Godot Version

Question

I am trying to create a particle effect where a projectile drops a trail of “breadcrumbs” along its flight path to help visualize the trajectory it took for debugging purposes. I have done this by making a basic GPUParticles2D node attached to the projectile that emits a small circle sprite with no velocity.

I first implemented this many months ago on a previous Godot version ~5 months ago and it worked as expected. Since this is only used for debugging specific behaviours, I have had it hidden since then. Upon reenabling it, I am seeing an issue where the particles seem to shake until the projectile stops moving. Has there been a change to GPUParticles2D that may have caused this? How can I fix it?

Here is a clip of the problem

I think I’m having this same issue. I have a RigidBody2D character that I attached a GPUParticles2D node to and when I move my character around the particles shake or even try to rotate even though I have local coordinates disabled.

Did this start happening in a recent update for you or is it something you ran into from the start? Might be worth reporting as a bug.
