In older versions, I used this combination (see image). Beginning from version 2020, stroke and shadow effects on a folder with Fill Layer do not work.
Hi, Thank you for finding this discrepancy. If you enable Preferences -> Performance -> Legacy Compositing, do the layer effects work again? You mentioned this is an issue for the drop shadow effect. Can you please share a screenshot, similar to your stroke screenshot, of this scenario? I’m not sure how a drop shadow would bee seen on the canvas when the canvas is entirely filled.
