2D Curve display is absolutely wacko on latest Mac build

Never seen anything like it.

One example attached.
Have restarted hardware and software; no improvement.

What it should look like:

Anyone else having a similar issue?
Recommendations besides downgrading?

Hello- please run SystemInfo in Rhino and post the results here.

Hello- see if un-checking ‘GPU Tessellation’ in Settings > OpenGL page does anything good.

-Pascal

Pascal,

That setting was un-checked in Settings.
However, enabling GPU Tessellation solved the issue.

Thank you
