    Hi everyone,
    I'm using Antergos Linux release 16.7 (based on Arch Linux) with the KDE 16.08.
    One of my 4 cores reaches the 100% from the moment I've launched Unity and it stays still until I close Unity.
    That's all.
    This doesn't happen when I launch the compiled project alone.
    I also tried Unity 5.4.0p1 on Kubuntu 15.10 on a different computer and the same problem occured.

    Thank you very much. I suspected this was known. I'll wait.

    Same issue here. On my Manjaro/Arch Linux box (using Xfce) one of my 4 cores is maxing out on 100%, as long as the scene is not in play mode (like discussed already).

    It is really really nice to see the Unity Editor running under Linux! But this issue kind of a show stopper in my case...

    It's a known issue. And it's the only thing that stops me from trying to use Unity on Linux.
    Also you can keep track of the known issues at the bottom of the first post in this topic.

    Yeah, I have reported this too.
    It's a known bug, it's been here for so loooooong that I a named this bug Spock.
    Spock can be hard to deal, but you kind of get used to him.
    Give a chance to Spock. <3

    I'm sorry for Spock, but no. :(

    Just wondering, do any of you guys check the temporary solution in the link I gave? I don't have Unity 3D linux right now (the download is huge and I'm on quota crap right now).

    I'll definitely check when I get home from work and let you know.. this has me excited, the CPU issue has been driving me absolutely mad. Thanks for the link!

    EDIT: It works!

    I've been using that for a while. It doesn't eliminate the idle usage completely, but it does bring it down from 100% of a core down to more like 8-16% of a core.

    Thanks aaulia, that solves the issue to a point where things become usable, nice! - Definitely better, than letting the editor rest in play mode all the time (previous "fix"), and then forgetting about it when working on something...

    I haven't tried the fix, and probably won't and will just wait for an official fix...
    But cool that it works! :)
