**Video explanation** base simulation, with noise enabled and overlayed.

**Exact steps for others to reproduce the error**
- Create any kind of Mantaflow gas simulation (if the emitter moves it is the most noticeable)
- Enable [[ https://docs.blender.org/manual/en/dev/physics/fluid/type/domain/gas/noise.html#bpy-types-fluiddomainsettings-use-noise | Noise ]]
