I am trying to understand how SurfaceFlinger/Composer works, especially on layers with transparency, blending or blur effects…
Layers with transparency seem to not “wait” the refresh of the layers below, creating sometimes inconsistent data (strange pixels, mixed-up between the below data and the correct data with transparency). - Does anyone know how SurfaceFlinger performs “blended” layer updates? - Does anyone encounter such effects? Notes: - I have tried with framebuffer in cacheable & in non cacheable memory with the same result. - I have tried with pmem in cacheable & in non cacheable memory with the same result.
