iMac late 2012 - How to enable beta blur ?

Currently I am experiencing annoying graphical bugs in Senoma, and I read somewhere that I should enable Beta Blur to fix most of the problems. But the option for me is disabled and I can not enable it. It says Log out required to apply changes to Skylight.

Does anyone know why and how to fix ?
