Its seeming like the gpu-facing cache is the one that needs invalidation from the GL/gralloc driver, but is not being flushed. This is a CPU/GPU coordination issue, and the GPU-based scenarios all work through the same cache and do not experience this problem. If we use overlays, this is not an issue, as the MDP/CPU cache sync seems to work. (Unfortunately, overlays are not supported on external displays)

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.
