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.

This bug is fixed on Oct 31, 2013 (#89 thakis@chromium.org)
and the fix will reach the stable channel eventually.
This is an issue with how Activity Monitor determines responsiveness – these processes are running perfectly fine.
(We changed chrome to work around that Activity Monitor issue, and the fix will reach you eventually, depending on which channel you use, how far we merge this, etc.)
