Color Points induce lagging even after deleting layer

[FloridaJo]

I created a vector layer to create a misty mountain.
Using color points made it extremely laggy so I instead went with a gradient and deleted the color point layer,
but the lagging was still there. Started a new project and only used gradient and there was no lag.
Somehow the cacheing or memory management is not correct in my opinion.
Anyone else experiencing this?
Here's a video of the problem:

Did you select all the points and hit the "Clear" button on the color points tool?

[FloridaJo]

yes, that works for a test file.
But on the other file that's not possible now since I deleted that layer.
But programming wise, deleting a layer should also clear them.

Can you try it on your existing layer anyway?

I think you are misunderstanding Synthsin. When you duplicate a layer, you duplicate all its proprieties too. If you didn't clear the Point Color in the original layer before duplicating it, then the new layer will also have that Color proprieties.

Yep, that worked.
Lag is gone now.
Thanks.

Actually I didn't duplicate the layer, I just copied the object and pasted it in a new layer.
Probably the same thing though since it was the only object in that layer.
