Rhino 8 line drawing AA issues

Hi @steve I see that when I draw a curve on top of an image the antialiasing is white:
This is in rendered mode, top view:

It also happens in shaded, but not as bad:

I also see that the antialiasing is too low in perspective view:
But it doesn’t look very antialiased. (And there are close to 0 difference between 2x and 8x on my RTX 4070ti)

Here also less intrusive in shaded:

Sidenote: F7 to turn off the grid doesn’t work in shaded, but it alters the colors slightly. It works in Rendered.

Strange, this worked when I restarted Rhino.
