Material preview thumb nails not showing

Hi There.
I need a little help.
I have just changed my desktop PC and re installed Rhino7. All seems find but the material rumbnails are showing all in black. Any idea why this is hapenning?

Hi @SINYW,

That’s probably a sign that you need GPU driver updates. Post the results of the SystemInfo command run in Rhino.

Hello Brian. That’s a good point! I will try that, Thanks!!
