Possible bug with Photoshop CC 2015.5.1
- Created an image with a Background Layer and a Smart Filters Layer. Two filters were added to the layer (Camera Raw and Noise Reduction).
- Attempted to create a border with Canvas Size
- Set a relative border size
- Border did not render accurately - truncated top and bottom.
- Flattened image and Canvas Size border rendered properly.
- Replicated every time I attempted.
- Have not had time to test otherwise.
