Curves do not show with gpu tessellation on

Using Work In Progress (6.0.17262.13121, 9/19/2017) build, no curves show when gpu tessellation is on. Even on new models I draw a curve and nothing shows up. This is unrelated to the monitor sleep cycle BUG that has been fixed.

What display adapter does your Options > OpenGL page show you’re using?

That should work just fine unless your drivers are old.
Run Windows Device Manager > Display adapters and see how old your drivers are.
If they are stale see if your laptop maker has updated drivers available for download.

Thank you for the suggestion. Updating the driver fixes the issue.
