Hi,

When I launch the game Heroes of the Storm on Ubuntu 16.04 with Unity 7, if I
try to switch between applications with Alt+Tab the screen of the game freezes.
I made a log but I don't any errors related to this issue, hope it will help
someone. Feel free to ask me something about this issue because it's very
annoying, you cannot switch between applications or take a screenshot with the
right key on my French keyboard.
