Hi.
So, I bought Peace, Death! on the summer sales and was wanting to play it after I saw Samsai streaming it. However when I tried to launch it, it didn't work. Steam starts the game and says it's running, as you'd expect, but closes it immediately, it doesn't even show the game window, the only thing that appears is the little steam window where it's written preparing to launch game or something.
I noticed that there was no steam_appid.txt in the game's folder so I created that and wrote the game's id in there (588690)- still not working. On the terminal it gave this error: Segmentation fault (core dumped) LD_LIBRARY_PATH=./lib:$LD_LIBRARY_PATH ./runner.
I the tried launching it directly from the terminal and got the segmentation fault error. I kept insisting and it eventually started. This is what I get when it boots properly:
Run_Start
Total memory used = 14060885(0x00d68d55) bytes
**********************************.
Entering main loop.
**********************************.
Texture #3 640,480
Texture #3 2048,2048
Texture #3 2048,2048
Texture #3 1024,2048
Window closed

vs when it doesn't:
Run_Start
Total memory used = 14060885(0x00d68d55) bytes
**********************************.
Entering main loop.
**********************************.
Texture #3 640,480
Segmentation fault (core dumped)

Both these outputs have lines before but are equal on both, at least from what I could see; I haven't checked them one by one.

If I insist with launching from steam it will also start.

I'm on Antergos 64 bit, just like Samsai. My specs are as follow: i5 6600k @ stock, 16GB of RAM and an AMD RX480 8GB with amdgpu (xf86-video-amdgpu 1.3.0-1) and mesa 17.1.3-1.
