cocos2d-x-2.2.2 memory bug

Hi all!
I was test hellocpp with wp8-xaml, I create class to show memory usage of game on screen.
When I press key window of device to run game on background then press key back of device to run game on foreground.
After each time, memory increased 4Mb. I don’t know how to fix it. please help me!
To show memory usage, add this code in function DrawingSurface_Loaded
LayoutRoot.Children.Add(new Utils.Usage());


usage.xaml.cs.zip (0.7 KB)


Usage.xaml.zip (0.5 KB)

Anyone help me please :((

I don’t know how to solve it too, may be in angleproject, seen in issue: https://github.com/MSOpenTech/cocos2d-x/issues/35, MS Open Tech works on it, thanks.

It looks like the problem is in DrawingSurface XAML control
