[Linux] The game sometimes does not quit

[u00101010]

Hi there,

This issue has been around for a really long time and it's pretty bothering.

Sometimes when I click on the Exit button in the game, and confirm the quit, the game freezes and won't quit.

I have to use the "kill -9" command to actually make it quit. (The regular "kill" and other force-kill options do not work properly. With other solutions, the window itself disappears but Steam will still detect DOTA 2 running.)

Currently I'm using Ubuntu 15.10 with Unity, however, this was an issue with 14.04 (also Unity) as well.

Usually when I don't actually play a game, just start the menu to check my items or something, DOTA manages to quit by itself.

Here is a Gist containing my System Information

Happened to me too, but will quit itself after 3 to 5 seconds later
