Worksession - Curves almost invisible when zooming in

Curves in a reference (inactive) file become almost invisible in a perspective viewport when I zoom in beyond a certain amount. It is repeatable. Images below show the viewport at two slightly different zoom amounts.

Any ideas how to remedy this, or is it a bug?

Hi David - I’ll see if I can reproduce this - you might, just as a test, disable Orca and close and restart Rhino to see if that has any effect - sometimes plug-ins can cause seemingly obscure and unrelated problems.
(not seeing it so far)
-Pascal

Pascal, it may be due to the large number of items on the layer, and the very large number of items in the attached files. I

@Pascal The problem appears to be related to number of objects and possibly layer structure. I can provide test files but they are too large to upload as attachments.

Updated to the latest NVIDIA studio driver and the problem remains. With 64 GB of system memory and 11 GB of video memory it should not be a memory problem.

OK - I tested with a few thousand curves - I’ll add some more - also, do you have multiple files attached?

-Pascal

I have the problem with one active file and one reference file. The reference file has 123,418 curves on 18 layers and sub-layers.

Important discovery - the layers with curves have to locked for the problem with the curves becoming faint when zoomed in. Unlock the layers and the problem goes away.
???

Yep. You got it. With locked layers I see the attached file display apparently overlaid with white at a certain zoom:


It does depend, it seems on other objects being in the file - I do not know yet if that is due to numbers or scene depth but I suspect the latter. Yep, objects behind the camera trigger this.
I’ll get this on the pile, thanks.
