I have the same problem with chrome since the last update. Also at the same time I got another problem - sometimes youtube videos and sound starts lagging like if I had 100% cpu load (which I dont have, cpu is at 10-20%) and youtube video starts randomly flickering. Mouse coursor is laggin too at the same time. Since all this happened right after EIS update I think it has something to do with the latest update aswell.
Running on windows 8.1, SSD with i7 and 32gb ram.
Edit: disabling behavior blocker works, like previous poster mentioned.
