I am using the 5.9.1 version,  
Issue is with the opacity option.

A soon as I reduce the opacity, the whole model sort of achieving zero opacity.  
Not sure, whether it is an issue with the PV compilation.

Any help/comments will highly be appreciated.

Thanks

Please use nvidia driver, if not possible, use mesa by using the `--mesa` option.
