Since the last WIP (I think from two weeks ago) curves, are appearing and disappearing, while orbiting and panning. This seems to be happening when zooming in closer to the curves. See the video and file attached. crv_behavior.3dm (3.6 MB)

Thanks for the reply. Those curves are actually quite close to origin. Around 140m distance… (the file I uploaded was in millimeters - forgot to switch that back to meters, but same behavior). [Bildschirmfoto 2020-05-22 um 22.31.26]

I don’t know what to suggest. I can’t duplicate the problem here. If you copy the curves into another file with the same setup does that fix the problem? If so, that might indicate some sort of viewport corruption in that file.

The file from above is actually a new file, where I pasted some curves from the original file into… This is not a huge issue, or maybe it is a small bug, that was accidentally caused and will be fixed in the next WIP. Here is my system info, if that is of any help: system_info.txt (9.1 KB)

Thanks. I’ve created a defect report: https://mcneel.myjetbrains.com/youtrack/issue/RH-58768 Hopefully the developer will find something.

Did you recently update you OS?

Thank you! Still the same behavior with todays WIP. Btw. it even happens when I create a new file and draw a single line, as can be seen in the video below! [image] stevebaer: Did you recently update you OS? I am running the current 10.15.4 Cheers

Try going to the OpenGL options in Mac Rhino and turn off “GPU tessellation” Does this make a difference?

Thanks; Apple led us to believe that they had fixed the issue with GPU tessellation in the latest OS update which was keeping us from using this feature. Looks more and more like this isn’t the case.

Sure thing! [image] stevebaer: which was keeping us from using this feature Do you mean GPU-tesselation? Does this run on the CPU if it is deactivated - hence does it speed up the viewport when running on the GPU?
