Subtracting rectangular path with radiused corners produces jagged corners, not curved

[Greg Lowitz]

I'm simply subtracting a rectangle (with radiused corners) from a background composite path. It looks good until I click "Subtract" in the pathfinder tool. After that, it looks jagged (not smooth). I read this could be related to a display artifact, so I toggled GPU off and CPU on, but this makes no difference. The resulting composite looks horrible. What else can I try? BTW, there is no stroke width on the shape. Is a stroke required for the subtract function to work correctly and cleanly? I don't recall ever doing this before. What else can I try? Is this a bug? See the two attached files. One is after I hit "Subtract" and the other is before I hit "Subract" - pay attention to the corners which are jagged. Thanks in advance for any help. This is preventing me from completing submission of my art. Also, when I print it, it also looks jagged, so it's not simply the display from what I can tell.

I forgot to mention that this is Illustrator (CC).

Which version exactly?

Can you share an example file?

How big or small are the objects? In some other graphics applications I've seen curves on objects or even letters get turned into straight line segments if the objects are scaled down too tiny.

If the rounded rectangle is simply punching through another object it might be worth trying to select both objects and use the Make Compound command.
