I upgraded to OS X 10.9 yesterday, and since then, one Google Chrome Helper is constantly red in Activity Monitor. I checked the PID (375) in Google Chrome's own task manager, and it is GPU Process. I don't think it is used often, but I also fail to see why it is constantly non-responsive.
Does anyone else experience the same thing? Is this a problem of GPU handling of the new OS? Maybe there are some GPU-accelerated websites/videos (I mean video player) out there so I can test whether there is a problem? Thanks.
By the way, my machine is a MacBook Pro 13'' mid-2012 non-Retina.
