Flickering points and inconsistent rendering with line MAT

Hi,

I’m trying to render with the line mat and am running into weird flickering issues.
The below gif is exported straight out of my project:
LINE MAT FLICKER
The point sizes and vector markers seem to flicker constantly. There’s no deformation or point-level animation happening. Point numbers are constant, too. It does this regardless of the geo I’m using, too.

How do I fix this?

Also, is there a way to thicken lines using the wireframe mat? In my project, the line width (in red) is set to 1000 and I’m still only seeing a relatively thin lines.

Thanks!

attached is my project file
