Ha, I bet this one will crash and burn over Fiji too.<p>More information here: <a href="https://wiki.ubuntu.com/MirSpec" rel="nofollow">https://wiki.ubuntu.com/MirSpec</a><p>They don't like X for all the normal reasons, they think Wayland might be like X but haven't investigated (I think you can replace the input handling in the "compositor" plugin; maybe I'm wrong).<p>They don't specify how they'll handle hard problems, such as:<p>- Client vblank sync (as well as compositor vblank sync). Compiz, unity, etc, don't do this now; clients run unsynced and tear.<p>- Switching unoccluded windows to render directly to the framebuffer instead of going through the compositor. Mandatory for good performance on something like a Nexus 10 (which has a 16MB framebuffer, so nearly 1GB/s bandwidth to deliver glClear at 60fps with no extra copies...).<p>- Handling multiple clients that want to read gestures. They actually say in their "INPUT" section that they will handle "shell" gestures "in the server", which sounds like they're going to bake their UI into their display server.<p>They want it to be compatible with all of the old apps too, which Wayland already does. I'm trying not to be judgemental, but it sounds like they want to write something like Wayland but without designing it first. Good luck with re-entry, guys.
