Preview Gaussian node freezes when decreasing scale parameter #11

Description: I encountered a performance issue with the preview Gaussian node in the GeometryPack. The node works fine when increasing the scale, but triggers a freeze when the scale is adjusted from a larger value to a smaller one.

Steps to Reproduce:

Set the scale parameter to a small value (e.g., 1.0) and run the workflow. It works normally.

Increase the scale to a larger value (e.g., 5.0) and run again. It works normally.

Decrease the scale back to 1.0.

The node freezes/hangs during execution. After next workflow run finishes, the preview window turns completely black.
