Hello - does this happen with any file?Say a new file with just a box? If not, can you please post or send to tech@mcneel.com a file that shows the problem, along with a link back to this topic?

I think I found an existing bug report for this.
Unfortunately, it is not open for public view:
https://mcneel.myjetbrains.com/youtrack/issue/RH-54879

It’s on the list and the developer knows about it.

Hi, thanks for getting back to me! It doesn’t happen with a simple box, but seems to happen with more complex shapes. I’ve attached a file (a solid extrusion of a closed curve with the clipping plane enabled) that displays a similar error. EDIT: The error only seems to happen when curves are present—if I hide the curves, everything works as expected. ClippingPlaneError.3dm (3.4 MB)
Here is an image of what the error looks like in wireframe view:
