Smart Object vs Pixel Object Bounding Box

When you’re transforming a Smart Object in Photoshop, the bounding box around the object looks different than when transforming a pixel-based object.

With a Smart Object, the transformation’s corner anchor points are solid dark grey, and there is an “X” that goes through the bounding box.

Pixel-based objects have no “X” going through them, and the corner anchor points have no fill.
