Erratic Display

My model started spontaneously displaying with a lot of errant lines (that dont exist). The display changes as I move in and out. its essentially a 2D drawing, but looks like its grown spikes!
Did I change a setting?
I’m also having trouble getting new objects to appear when I draw them.
What have I done?

Hi Kelly, this is a OpenGL artifact. Updating to the latest Rhino Mac should resolve this. If not please send us the file and reference this post. Rhino - Upload to Support

Can you type SystemInfo into the command line and paste the results here? Thanks.

Your macOS is a couple updates behind as well.
12.5.1 is current, and you’re on 12.3.1

I restarted my computer, and I am not seeing the errant lines now.
Thank you.

I’m not seeing anything (slightly different setup)

One thing you can try is switching the GPU Tessellation off/ reduce the anti-aliasing (less info going into the OpenGL pipeline). It located in Preferences>OpenGL
