Weird black shapes appear in viewport

Hello everyone, I’ve ran into an interesting issue where, whenever I create any 3D geometry (even something simple as ‘Box’) I will get these interesting but wierd and definitely unworkable black shapes in the viewports. I’ve attached an image of the issue.
Selecting the geometry instead of the point will turn the shapes Yellow instead.

For good measure I’ve just downloaded Rhino 5 to see if it’d work there.
Strangely there’s no issues in Rhino 5.
It also changes depending on how I have my model/geometry shown in the viewport.
Setting it to ‘Rendered View’ and/or ‘Technical’ (instead of the usual ‘Shaded’ and ‘Wireframe’) will also get rid of these shapes…
My suspicion is that it’s related to running Rhino 6 on Windows 7, but the two of them should be compatible.

Hi @marcvanhal,

Could you paste here the text from the Rhino _SystemInfo command?

I would recommend you check whether there is a newer version of your Intel GPU from here:

You current driver seems to be almost 3 years old.


Yeah, that was the first thing we tried.
While installing the new drivers though, we always get the message stating that our current driver is newer.
So that’s quite weird as well.

Well, I’ll just keep on digging. If/when I find a fix, I’ll come back here.


I would suggest manually uninstalling the current Intel driver and then install the one downloaded from my link.
