Not sure when that change was introduced, but I just noticed that in Rhino 7 when turning on the “Use advanced GPU lighting” option for the Ghosted viewport mode, all the curves and points are no longer visible through surfaces when in Ghosted view. Is that a visual bug, or is intentional change to speed up the rendering in the scene?
I use Rhino Version 7 SR6 (7.6.21110.13001, 2021-04-20), latest Nvidia drivers and Nvidia GTX 1660 Ti.
Notice the two blue curves on the right side of the Rhino Options pop-up window. They are visible if I turn off the “Use advanced GPU lighting” option.
