How is this generating drop shadow?

Hi there! 👋

Thanks for sharing the screenshot, it really helps to see what is going on.

I think the drop shadow is probably added to one of the nested layers inside your frame, not the main frame itself. Since Clip content is unchecked on the right, the shadow from an inner layer can show outside the frame. Try looking at the layers under this frame in the left Layers panel, and you might find the shadow there.

Hopefully, you will find it! 😊 If not, feel free to share what layers the icon has, and we can find the problem together.
