Not prefect align to pixel after Expand Stroke
Drawing with Rounded Rectangle Tool, then convert the outline with Expand Stroke command, you will see it's not perfect align to pixel, gif capture below: (sometimes get worse result than this) click gif ↑ to see the animation.

I believe WaveF is referring to the "bend" of the shape when converted from a stroke to a curve with the Expand Stroke command. This is already logged to be looked at.
