Edges disappear/ plane-clip as they approach section cuts in perspective view New Graphics Engine

[Rodog]

As per the title, its only when New Graphics Engine is turned on. Edges progressively appear and disappear as you zoon close to the cut plane. The issue resolves with Classic Graphics on:

Jamb_New Graphics_Perspective:

Jamb_New Graphics_Parallel

Jamb_Classic Graphics_Perpective

Jamb_Classic Graphics_Perpective

I’m using the latest SU 2027 however I’ve noticed this for some time, possibly since the new graphics engine was introduced in 2024.
I imagine this has been noticed or discussed already, I perhaps just didn’t type the right search terms to find it.

I see this in your model, too. Also the edges extend above the section cut from other angles.
