apitrace from the starting of the game until entering of a tactical mission and
subsequent crash

X-Com Enemy Within from Steam crashes when entering a tactical mission. The
globe part of the game works just fine. This happens with AMD Radeon R7 360 gpu
which I just installed. I had previously HD5750 (Juniper) which ran the game
just fine. The crash happens always when entering a tactical mission.

Apitrace and other logs are attached.

I'm running Gentoo.
