[HELP] My polylines disappear in rendered view the closer I view them / closer I get to vertical (top) view

When I look at my polylines in rendered view from a distance i can see them all clearly, but the more I zoom in or the more I look at them from above the more they ‘fade ouy’ till I can not see them from close / from top view. What is the problem here?

Is it far from the origin?

That doesn’t fix it for me;

I had already moved them all as a whole to 0,0,0.
This is my view shaded and I can move around freely without anything ‘fading out’.

Bonus: If I want to print it then it does show the polylines on the preview.

Hi - please run the Rhino SystemInfo command and copy-paste the result here.

This might sound very dumb, but I hadn’t tried restarting rhino when I asked the question, a simple restart fixed it alot for me, but somehow I still have a few polylines that fade out, I can’t see anything that separates these polylines from the others.

Hello - I doubt this is the problem but it would not hurt to disable Enscape in Options > Plug-ins page, then close and restart Rhino - does that change anything?
