Whats going on with the materials preview lately?

[Yambo]

All the Octane materials previews went nuts lately.
Screen cap attached.

Ahmet, as far as i understand it's something from Maxon side, but we got to have some solution for that.
Any news?

Thanks

Hi Yambo,
maybe an nvidia driver issue?

1-If you see unvisible materials that's about me+transparent ogl implementation on latest builds. There is a bug in maxon sdk but i've kept this feature active anyway. Just i've tried to fix with some hacks as much as possible.
2-If you see weird dots, colors, lines that's a problem on renderer+driver+gpu. Not about me or maxon.

More like crazy dots, lines, artifacts.

Let's try to update Nvidia driver. As far as you guys know - Is it safe to update to 372.90?

So if I apply some simple material without any alpha or opacity and the object disappears in the viewport, I cannot do anything against it at the moment? If I reopen the file, everything is back to normal.
Gonna update my driver and see what happens

edit: ah. just disabling opacity does the trick.
