That's black flickering - there's been a few gfx bugs related to this in the 1.2 timeframe. Might be a dupe of one of those bugs.

For the koi? nom btw - this is blocking getting a target 1.2 partner application working on FxOS correctly.

It might be related to Bug 917444, if the game uses 2d canvas.

I received the app from paul yang. It seems the dup of Bug 917444. There are two way to solve the problem.
- [1] Ensure frame complete by reading one pixcel (Bug 917444)
- [2] ANativeWindow backed EGLSurface (Bug 767484)

For the short term(v1.2), we are going to fix the problem by [1]. For long term, [2] is going to be implementad.

By applying [1], I confirmed that the problem was fixed.
