Visual BUG on rhino/grasshoper

Hello everyone,
I just started using rhino and grasshopper together. I have created a small box but there seems to be a visual bug see picture attatched. Does anyone have a clue on how to get rid of it ?
Don’t hesitate to ask for more precisions if needed. Thank you for your help

Hi, welcome to the forum!

Please post the Grasshopper definition file - it is hard to judge what is going on from a screenshot.

Here you go, thank you for your help.

I do not see these solid cylinders when I open this in Rhino 8 SR9. Are you using that version?
Do you have any changes to your display modes? If so, what happens if you reset the display mode to default?

Good morning,
I put my settings on default and updated my rhino to SR9 but the problem is still there. On an other note the “zoomin” in the perspective view is limited ( can’t zoom very close to the box ) , is it normal ?

The problem seems to be with surfaces only. Meshes are rendering properly…

Hi Burger,

Please run SystemInfo in the Rhino command line and post the result. Thanks

Ah, your graphics driver is over 8 years old. Please update to the most recent version.

I updated my graphic drivers and everything works great now ! Thanks to both of you.
