The problem looks like a cpu cache problem.
We call gralloc's unlock function, and digging through the gralloc code, it looks like the internal native buffer flag that should trigger a cache flush is behaving properly. Now seeing what I can find out in the kernel....

Title:
  Severe graphical corruption (mostly horizontal streaks/lines) running
  software clients (including Xmir) on android

Status in Mir:
  In Progress
Status in xorg-server package in Ubuntu:
  Invalid

Bug description:
  I'm seeing severe graphical corruption running mir_demo_client_flicker
  on mako.

  Start a few instances of the client (or just one flicker and some
  other clients) and you'll see the mir_demo_client_flicker window
  contains significant corruption.

  I don't think it's an overlays issue. The problem occurs even without
  overlays.
