Safari Web content generate 99% CPU usage

Hi There,

I've experienced a problem with the use of safari on my new Macbook pro 13. One safari was running, a process gets stuck and generate a usare of 99% CPU and in some cases a total kernel crash. Once in the apple store they've told me that it was linked to Adoble Flash player and i had to remove it. Now, i'm not using the plugin  anymore, but clearly i need it for some video stream. I've looked in the Flash Player 21 Release Notes and found this :

April 21, 2015

In today's release, we've updated Flash Player NPAPI for OSX to resolve a bug that was impacting certain Mac video cards.

Does this mean you've solved the problem?
