Surface edge and isocurve issue

Hello,
Great to have started using Rhino 8 WIP!
I’ve noticed a glitch. I have some picture frames in the scene with images on them. When they are visible, edges and isocurves on other surfaces in the scene seem to disappear and reappear at random. If I hide the picture frames, this behaviour stops.
Thanks,
Sach

Do the PictureFrames and other objects coincide? Try moving the picture frames forward or backwards?

Hi @davidcockey
No the objects don’t coincide. I’ve been working on exactly the same file in v7 without this issue.
Thanks

Hi -

Please start with updating your GPU drivers and see if that makes a difference. 2019 and 2018 are “very old” when it comes to GPU drivers.

@wim
That’s a good point… I’ll update.
