Short description of error
The controllers of the Color Ramp ore the attribute color Ramp flikker in Size when you move the Node.
Exact steps for others to reproduce the error
Create a Color Ramp in the Geo-Nodes Work Space (Attribute Color Ramp) ore in the Shader Nodes Workspace and move the Node around. You will see that the controllers will change the size. For me it was only in some zoom points.
