[Linux] UE4Editor crashes after loading project

Hello, I’m quite new to Unreal Engine 4 and I wished to use it. However I had some problems to make the Editor works… I’m running on a fresh Ubuntu 16.04 64Bits, I have an Intel Core i5 CPU 760 (2.8GHz) as CPU and an AMD R9 280 as GPU. I managed to use UE4 a while ago when I was on Windows but now it just don’t seem to work at all…

The project browser works fine and I can both create and see the projects I made but when I try to load one of them, UE4 just “opens” a transparent window after loading the project then closes immediately. Here’s the log file :

Thanks for taking a bit of your time to read that.

Ps. I’m french so I apologize for any unwanted mistake…
