I open Sublime 3 - Stable Channel build 3065, in Ubuntu 14.04LTS with Unity, then switch to any other window, then back using alt-tab and Sublime doesn’t come to the foreground. I have to minimize every other window to see it.
Additionally, when I click on the icon in Unity, it also doesn’t come to the foreground. It’s been going on for several days now.
Thanks for looking into this!
