Wine log (The Witcher 3 hangs system)

Since update of wine-staging to 2.2, Witcher 3 started hanging hard on startup.
The screen goes black, and keyboard becomes completely unresponsive. The system
can still be rebooted if accessed for example from another machine over ssh.

OS: Debian testing, x86-64, KDE Plasma 5.8.4.
Graphics: AMD RX480, Mesa / Gallium 0.4 on AMD POLARIS10 (DRM
3.8.0/4.9.0-1-amd64, LLVM 3.9.1)

See attached Wine log.

My Mesa is Mesa 13.0.4, but same happens with more recent Mesa as well.

--- Comment #2 from Sebastian Lackner  ---
Could you please test if the issue is related to CSMT, or does it occur always?
Also, if possible please try to check (for example via SSH) if the system is
running out of CPU or GPU memory.

It occurs both with and without CSMT. I logged in remotely, to check the
system. CPU / RAM usage were normal. Any suggestion how to check VRAM
utilization?

I tried using something like:

GALLIUM_HUD_DUMP_DIR=$HOME/tmp GALLIUM_HUD=VRAM-usage ...

To dump data to a log, but it hangs before Mesa starts logging anything
apparently (the log file is created, but it remains empty). radeontop doesn't
like Debian testing kernel, as they note:
> For the amdgpu driver, only the mem path is
> currently supported - for those cards, this
> means radeontop won't run on the default Ubuntu
> kernels that block /dev/mem

so it can't show VRAM utilization.

This is likely caused by an infinite loop in a shader. I don't think the bug is
specific to wine-staging. A +d3d_shader log might give some pointers. Anyway,
this should be fixed soon when some missing shader instructions are
implemented.

Witcher 3 hanging run with +d3d_shader

Attaching the hanging Wine run log with +d3d_shader (using latest build of Wine
from git master: wine-2.2-159-g0dc677c05f).

I was having this problem too, and I solved it by commenting the
glDispatchCompute() call in wined3d/drawprim.c.
I re-enabled it yesterday, and it's not crashing anymore. So I guess it was a
problem in the Wine compute shader implementation, that seems fixed right now.
