Zig zag line appears around edge when I create shape with gradient and opacity

[Jeremy2340219157lv]

When I create a shape using the pen tool, and then fill with a gradient that has some opacity on some or all of the parts of the grad, a zig zag line appears around the edge which I can't get rid of. I went to'Apperence' and switched off the stroke, but this still didn't rectify the problem.

Can anyone please help solve this issue?

Hi Jeremy,

could you attach a screenshot, please?

It sounds like a GPU preview problem.

Try Cmd or Ctrl E to switch between GPU/CPU preview.

Thanks Ton, I tried Cmd E and that's now got rid of the zig zag line.

Many thanks for your help, much appreciated.

Good to hear that helped. It is just a preview problem and will not affect print or export. I often switch with Cmd E if I don't trust the preview.
