RC4 Android Emulator Rendering


I’ve recently updated my project from RC3 to RC4 and since then, on Android Emulator, when i build the app, even with crosswalk, every components have a rendering problem, they are invisible.
We still can interact with them, they even turn black when clicked, we can navigate but they are invisible.

After some search it look like it’s since the css property contain was added to the projet but i’m not sure.

On a real device we don’t have this problem.

Anyone? Am I the only one with this bug?

we need more information.
How could we test this?
Does this happen on a starter project?
