When I pause my game, my GPUParticles2D node seems to pause correctly (the particles freeze in place). However, when I unpause after waiting a few seconds, it seems that the particles engine has continued to run during the pause, and the particles then suddenly “catch up”, rather than continuing with their expected behavior from before the pause.
Here is a short video - you can see that after the pause, the bubble particles sort of zoom sideways toward the player, rather than coninue gently floating upward (which is the expected behavior, since that is what would happen without pausing and unpausing):
Here are my settings for the GPUParticles2D node:

Is there a way to get the bubble particles to behave exactly like they would if I had not paused and unpaused?
I’m relatively new to Godot, so I’m not sure if there’s a setting I missed, or whether this might be a bug. If it’s a known bug, is there a workaround?
Well, I went through each Process Material setting that I had enabled, turning them off and on to see if anything fixed the problem.
It appears that turbulence is causing the problem you can see in my videos. After I turn off turbulence, there is no particle drift after a pause. Turning off turbulence also fixes particle drift during a pause when interpolation is enabled.
