Hot spots: Function of DoF? Or fstop value?

Only occurred to me this morning.  For a given lens on a 1.5x crop, it has same DoF as a full frame camera, a full stop higher.  Example: f5.6 on a 1.5x crop is the same DoF as f8 on full frame.  So if a hot spot shows at f16 on full frame testing, it will show up at f11 on a 1.5 crop?

Or are hot spots a function of the aperture blades of the lens, which are constant for a given fstop value?  Curious.
