When an entity is partially behind or intersecting the camera near clipping plane, raw WorldToScreen math can produce inverted projection artifacts.

Checking clipW < 0.01f or performing homogeneous polygon clipping against the near plane (w > nearPlane) prevents screen-stretching glitches.

Adding a simple frustum boundary check before rendering the box vertices keeps the overlay completely artifact-free.
