Issue with Osnap

Hi, I´m having issues with Osnap. Sometimes the cursor snaps to nothing outside the geometry and stays there. It does not update when I get closer to ends or midpoints where I want to snap the cursor to. Tried to replicate the problem in the video above.

Never had the issue before and its really annoying since I´m using the function all the time. Started a few weeks back. Is this a setting or is it a bug? Using rhino 8 on a MBP 2024 M3 Max.

Could you run SystemInfo in the command line of Rhino, and copy - past all pop content here? Thank you.

hi, see systeminfo below:

I´m starting to wonder if this problems only occurs when modeling small objects, like 10x10mm. Which I happen to have done quite a lot recently.

Could you give it a try with Rhino 8.23 ? Thank you.

I updated to the latest version and the issue persists. And it is not only when the objects are really small unfortunately.

i assume you have center snaps activated, it at least looks like it at about 10 seconds in it snaps to the center for a split second, it is pretty dominant. if so deactivate it and see if that improves your situation.

you also have smarttrack enabled, just in case maybe turn that off either if you dont need it. it can be a bit bothersome with all the extra snaps indicators but that might not be causing the issue.

I know, but either way rhino is behaving weird. It does not matter if I have osnap or smartrack active unfortunately.

Could you please update to Rhino 8.24 and try it again? Thank you.

For some reason the issue disappeared with this update. Was there a bugfix for this? Thanks!
