Hello !
I don’t know if I can report a bug here bug it’s the only place I found so …
I’m using Sublime text 3 Build 3114 on Ubuntu 14.04 and Gnome shell.
Sublime text freeze when I launch it, i see tue UI but I can’t switch tabs, can’t do nothing … until I minimize the window, this refresh the whole thing and no more freeze during the day 
Anyway I love Sublime, good job guys !
