No need to take a look. A driver updated fixed the issue.
Hi @DavidEranen - unfortunately I am seeing this glitch re-emerge even after updating my graphics card. Here are my current stats:
NVIDIA Corporation
Quadro K2100M/PCIe/SSE2
OpenGL version: 4.5.0 NVIDIA 376.33
Render version: 4.5
Shading Language: 4.50 NVIDIA
Driver Date: 12-11-2016
Driver Version: 21.21.13.7633
Maximum Texture size: 16384 x 16384
Z-Buffer depth: 24bits
Maximum Viewport size: 16384 x 16384
Total Video Memory: 2 GB
I’m using this build:
Work In Progress
(6.0.17003.8321, 01/03/2017)
What’s strange is it was working fine for a while - it wasn’t happening at the beginning of my Rhino session but now it’s started again. I was playing around with different display modes (like Arctic) and doing some hi-res screen captures with ViewCaptureToFile. Let me know if there’s anything I can do to test to help get to the bottom of the issue.
It’s also happening on my other machine, which has a totally different card. So not sure that’s the issue…

Only transparent material display from grasshopper seems to be affected. Using custom preview w/ an opaque material registers no artifacts.
andheum,
We’re currently working on fixing an issue similar to this. Thanks for reporting!
This problem is back in the latest Beta, though it seemed to have gone away for a while.
Thanks, I’ve reopened the issue.
incidentally, that’s a 3d model of the tattoo I just got. Drew the mockup with procedural stippling in grasshopper 
First Rhino/GH-designed tattoo?

Did you apply the tattoo with a robot controlled by Grasshopper?

Does this only happen with Grasshopper geometry or does it happen with old fashioned Rhino geometry too?
only grasshopper geometry.

Can you share your model with me? @DavidRutten and I both can’t repeat the bug with our attempts, and no I’m not asking just so I can get a matching tattoo
