CIMGeometricEffectOffset not working in JS

The below is my code which creates a line, I want to see it offset a certain distance. It works in the legend but it results in the line ultimately not drawing in the map itself.

{ type: 'CIMSolidStroke', effects: [{ type: 'CIMGeometricEffectOffset', method: 'Rounded', option: 'Fast', offset: 3.0 }], enable: true, capStyle: 'Butt', joinStyle: 'Round', width: 3, color: [ 56, 168, 0, 255 ] },

Is this method supported?

Hi @martip23 - yes, this method is supported! Here is an example using the same symbol layer you mentioned above: https://codepen.io/annefitz/pen/eYgPMWP?editors=1000

The green stroke symbol layer is offset by 3 and the red stroke symbol layer has no offset applied. Let me know if you have further questions!

Thank you! I got it to work now, it seems to take at least 2 minutes to load, and sometimes it generates incorrectly. I think I have too many polylines to get this to offset efficiently.

Interesting, I haven't seen performance issues with this in the past. Would you be willing to share your app with me? You can email me at afitz@esri.com if you don't want to share it publicly here. Thank you!

I sent some information via email. I should also state, that sometimes when it does load, and loads buggy (Only sections of one or two of the hundreds of lines loads), it fixes itself when I zoom out completely, and zoom back into the map.

Note that when I remove the offset effect, the lines load instantly.
