Strange slow down and frozen like behaviour of Google Chrome Version 40.0.2214.115 (64-bit) on Yosemite

Do you also start facing such strange Chrome behaviour?

I am facing it mostly when browsing websites like YT with flash content. The browser freezes and I can not do basic things like e.g coping the selected text...

STRANGE: Chrome Version 40.0.2214.115 (64-bit) OS X: 10.10.2

DISCLAIMER: I got my Macbook PRO retina 3 days ago from service, where they replaced graphic system (whole logic board).
