Unity 4.3 does not allow alpha compositioning with other Android views

Formerly, switching the platform settings to use 32bit display buffer turned all texture with alpha to display underlying Android view elements. This was useful for video overlays, compositing Android view hierarchies with Unity gameplay scenes, etc.

However, in 4.3, this functionality is no longer accessible in the same way. The only clue is from here:

Unity 4.3 change log states, “Android: 32bit display buffer without alpha is now the default to avoid compositor bugs on android.”

Our project depends on the 32bit buffer with alpha. We show a movie using the native player below the unity Surface, with opaque Unity elements on top. That surface is transparent over where the video is, everything works out.

However 4.3 broke that. Any idea how to “undo” that new default or recreate 4.2 functionality allowing view compositing in 4.3?

I am running into this too!

All of my Unity 4.2 projects that functioned correctly in Android, display blank Android screens after updating to Unity 4.3.
The updated projects seem to function correctly in Android if the 32-bit display buffer checkbox is checked before building.
With Unity 4.2, I never needed to check the 32-bit display buffer for the apps to work correctly.
