Android surface flickering between buffers

Question

I am having a problem with my Android system. It is running on a custom platform and when I boot up the device the screen flickers between the bootanim and the console "A N D R O I D " screen.

When the bootanim redraws itself it is visible but then it quickly flickers back to the "A N D R O I D " screen.

I suspect that this is due to some setting of SurfaceFlinger or OpenGL however I can't find much documentation on then - except the source.

Do I need to define something in my device configs specific for my platform?

Answer 1

I have managed to fix this issue.

It is related to the kernel config. To stop the 'flickering' I needed to unset CONFIG_FRAMEBUFFER_CONSOLE.

My bootanim now displays beautifully...!
