BUG: Duplicating A Layer Has Content Disappearing On The Canvas

I see what you are talking about now. When you drag the layer if it's visible, the image in the layer disappears on the canvas while you decide to create a new layer or throw the layer away, temporarily hiding it until you choose. Yes, it's doing this on my Mac too. I don't see an issue with the behavior but I normally use a keyboard shortcut to duplicate.

Melissa thanks for your reply - but this behaviour (and maybe I wasn't specific enough) is happening when you drag the layer itself. When you let go of the layer with your mouse - it re-appears.

Try resetting your preferences. It's not happening for me and it's not new behaviour. What happens if you use the keyboard shortcut, cmd + J to duplicate the layer?
