Hi Raj,
I just integrated liaocheng commit to my version of away3d. My application is only for desktop flash player so I haven’t tested on Android.

I have updated Away3D libs to Gold 4.0.9, but the context3D.dispose() issue is not fixed yet in that release. Which branch should I merge to work with the 4.0.9 SWC? I gave the particlesfeature branch a try, but I received a few errors, maybe because of the incompatibility with the SWC.

With Away3D 4.1 alpha, I had to fix Stage3DProxy to make it works.

See my post http://away3d.com/forum/viewthread/3505/

I have just upgraded from 4.0.9 to 4.1, but the problem is still there.

I can’t use the fix by Cheng as the corresponding classes are very different.

What can I do to fix this problem in 4.1 (master)?
laurent fix is not sufficient.

Well, I have explained my problem in this post a few months ago

Recently I have discovered that on a MacBook (in Safari) the performances are terribly low, and when context is disposed (setting fullscreen) the background disappears (view3D.background), while the other 3D elements remain visible (you can see the result in the scrrenshot in the old thread): at this point the game becomes a lot faster. Is it possible that the background is so heavy on stage3D?
Anyway, I need to fix the context-dispose bug, any idea on how to fix it on Away3D 4.1?
It looks like I need to restore the background only, as the other 3D elements are visible.

By the way, can you suggest an alternative way to display a BMP background?
