Android Chrome and Opera FPS drop down cocos2d-js

Hello,

Today I upgrade Chrome and Opera on Android and tried to run my games. But FPS dropped down from 35-40 to 5 FPS. Opera shows 2 FPS!!! I tried Canvas or WebGL modes. And it is not game scene - but Main Menu with 5 sprites only! Same thing with the Test Cases! I tried on Galaxy Tab 3(Android 4.4) and HTC One S(Android 4.1), and I got same result. I also tried to upgrade cocos2d-js to 3.6, install Opera Beta and Chrome Beta, but I nothing changed.

Does anybody else have same problem?

Thank you!
