Android 4.0.x Canvas blinking/flickering (cocos2d-html5 2.2.3)

Hi,

I’ve been working on a game for some times now, just to discover that on Android 4.0.x (with devices containing 1G memory) the canvas will blink/flicker entirely after playing for sometime(30min to 1H, sometimes right away).
There’s no error whatsoever.
It sounds like a Android 4.0.x problem but if somebody has any idea on the matter(solved it, experienced it)
any feedbacks/comments would be appreciated!
