Thanks for alerting me. I’ll have a fix posted shortly.

I believe the bug you are encountering is due to a driver fix. We recently fixed a bug where the driver incorrectly accepted built-ins without redeclaration.

Yup, I have the same issue on a 680m gpu.

Updated drivers to ODE 310.90. Issue is still there :(

Bump

Bump again, two month passed…

Here is a fix since nvidia doesn’t care to post one…
