Save Game to reproduce the bug

Hi there.

I get reproducable system freezes when playing The Witcher 3. The save game
that lets me reproduce this quickly is attached (requires The Witcher 3 with
all Add-Ons).

I've reported this bug it wine first but as far as we could firgure out it is
more likely a bug in mesa. You can find the wine bug report here:
https://bugs.winehq.org/show_bug.cgi?id=43273

I'm using an AMD RX 460 on Arch Linux with Mesa 17.1.4.

I don't know how to debug this further since I can't do anything as soon as the
freeze happens. The game music keeps playing. Sometimes Ctrl+Alt+FX lets me see
the TTY, but nothing reacts afterwards and the game music stops.

There is nothing possibly related in the journal or Xorg logs.
