All,

It's been a while coming, but the pieces are almost all in place for what could be a significant performance boost to Unity 8.

It started with basic occlusion detection in Mir:
https://bugs.launchpad.net/mir/+bug/1227739

And then recently progressed with opaque pixel format support:
https://bugs.launchpad.net/mir/+bug/1240833

So now the only piece missing is a fix for platform-api, to choose a non-alpha pixel format by fixing:

static MirPixelFormat
mir_choose_default_pixel_format(MirConnection *connection)
{
    MirDisplayInfo info;
    mir_connection_get_display_info(connection, &info);
    return info.supported_pixel_format[0];
}

(https://bugs.launchpad.net/mir/+bug/1227739)

When all put together with Mir 0.1.2+, I hope you will find the Unity8 touch experience to be noticeably smoother.

- Daniel
