g.reventlov: I'd like to replay this game. The first time that I played it, a year ago, it worked flawlessly, but now, when I launch it, it hangs immediately, without showing anything. One CPU core at 100%.

libSDL2 is installed.

I tried the usual trick for unity3d games, creating a ~/.config/unity3d/CampoSanto/Firewatch/prefs file with

<unity_prefs version_major="1" version_minor="1">
<pref name="Screenmanager Is Fullscreen mode" type="int">0</pref>
<pref name="Screenmanager Resolution Height" type="int">1080</pref>
<pref name="Screenmanager Resolution Width" type="int">1920</pref>
</unity_prefs>

But I obtain only a blank window frame: https://i.imgur.com/aOgcmFQ.png

This is the console output:

Many packages, kernels and nvidia drivers have changed since the last time it worked, so I can't say if this is the result of a system update, and which one.

My system is:
- Linux arch 4.16.3-1-ARCH #1 SMP PREEMPT Thu Apr 19 09:17:56 UTC 2018 x86_64 GNU/Linux
