Kingdom Come Deliverance (379430)

Occurs on proton 3.7.3 and 3.7.4 installed with steam

Logs from proton default logging config:
steam-prune-379430.log

Each time I've seen the system crash, I've seen the following lines in journalctl:

Aug 24 17:37:37 HOSTNAME kernel: [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, last signaled seq=64337, last emitted seq=64339
Aug 24 17:37:37 HOSTNAME kernel: [drm] GPU recovery disabled.

A journalctl log from when I left the machine running after the initial hang:
journalctl-crash-379430.log

Finally a workaround to get the game to get past black screen:

Needed to copy d3dcompiler_46.dll and d3dcompiler_47.dll
from:
~/.steam/steam/steamapps/common/KingdomComeDeliverance/Bin/Win64Shared/
to:
~/.steam/steam/steamapps/common/KingdomComeDeliverance/Bin/Win64/

Further, this game DOES work under wine 3.12 staging, with DXVK 0.64 (Configured with Lutris)
dxvk--lutris.txt

When i use the above configuration, I do not see the errors described above.

Game logs for those who care:
Launcher.log
kcd.log

System Specs, short:

Ubuntu 18.04
AMD RX 480x w/ amdgpu-pro-18.30-633530 (--pro flag enabled)
Linux HOSTNAME 4.15.0-33-generic #36-Ubuntu SMP Wed Aug 15 16:00:05 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
Desktop environment: i3wm

System Specs, long:
steam-system-report.log

Start by reviewing steam-prune-379430.log, journalctl-crash-379430.log, Launcher.log, kcd.log, dxvk--lutris.txt, and steam-system-report.log alongside the Proton 3.7.3 and 3.7.4 context. Reproduce the black screen and system hang with the stated Ubuntu and AMD setup, then compare behavior with the documented DLL workaround; done means the game starts without the reported hang or crash.
