Rhino 8 - lose lines on objects when zoomed

It seems linework on objects is not working properly on Rhino 8.
In Shade modes, lines are suddenly thicker when zoomed close (I have it all on 1 for thickness), and lines just disappear on Render (turned on line as thickness 1) when zoomed closed up.
The screenshot shows most lines are disappeared, but some lines for surfaces still show up. It doesn’t happen all the time, but happens frequently.

Please post both a simple 3dm file and the output of the Rhino SystemInfo command.
-wim

I can’t send the current project file, but here’s a test file. I couldn’t replicate the same issue of disappearing lines (maybe the file is not complicated enough yet?), but I found a new strange graphic error. When zoomed in ‘rendered’ view, a little bit of lines at corner show up–see attached image.

It was never solved. I still have the same issue constantly, and McNeel hasn’t acknowledge the bug.

I’ve found increasing the edge width to 2 pixels stops them disappearing when zoomed in…
