Is your GPU an Intel HD 4000? I’ve seen this behavior only with that specific GPU.

Hi @KeithR , Can you run the SystemInfo command in the WIP and paste that text here? I bet Steve will need that info too. Thx

Thanks; this sure looks like the same Intel driver that is not working with Rhino’s GPU tessellation feature. I’m going to try and have Rhino detect this driver and disable GPU tessellation when it notices that driver.

I’ve created a bug report to detect this specific driver and disable GPU tessellation in that case.
