When switching to WebGPU renderer, we will get the following error. It seems that our grids have something wrong.

Error while parsing WGSL: :158:25 error: smoothstep called with 'low' (1.0) not less than 'high' (0.0)
                alpha = smoothstep(1f, 0f, (length(_e266) - ((BASE_DOT_SIZE * _e268) / _e271)));
