The good news is that the new PG WU's now work after installing CCC 10.11 APP along with the Open CL; the bad news is that after installing 10.11, I now have problems with my monitors.

I have (3) monitors and I am having this strange flicker problem with not the primary monitor but the other two, never at the same time though. It seems to only occur when I either have a browser up with intense graphics or when playing EVE online.

Saying it flickers is an understatement, it's hard to explain. Is anyone else having a similar problem?
