            Bug ID: 108531
           Summary: [DXVK] GPU hang with Megadimension Neptunia VIIR
           Product: DRI
           Version: unspecified
          Hardware: Other
                OS: All

dmesg, card0/error and save

In the game Megadimension Neptunia VIIR, when the player tries to enter in the
map Jingu Sakura Park - Inner a GPU hang happens. As the game saves in that
part, loading the save again makes the GPU hang again in such way it is
impossible to do anything with the save, rendering it basically useless. 

Steps to reproduce:

1) Install Steam;
2) Enabled Steam Beta;
3) Enable Proton, minimal version 3.7-8;
4) Install Megadimension Neptunia VIIR;
5) Play until reaching Jingu Sakura Park;
6) Try to access Jingu Sakura Park - Inner;
7) Notice GPU hang.

As the game play to reach would take up to 6 hours (performance is REALLY BAD,
be aware), my saves are attached too. The remote directory should be copied to
$WHERESTEAMISINSTALLED/Steam/userdata/$USERNUMBER/774511/. Save 1 and 3 are the
relevant saves.

This happens 100% of times, everything I tried (older Mesa, stable Mesa, DXVK
from git, 4.17.19, drm-tip) failed.

The attached file has dmesg, card0/error and the saves. dmesg is corrupted
because of https://bugs.freedesktop.org/show_bug.cgi?id=107945 but is still
readable.

System specifications:

Processor: Intel Core i3-6100U;
GPU: Intel HD Graphics 520;
Architecture: amd64;
Mesa: 18.3.0-devel (git-fdd926d5b2);
Kernel version: drm-tip (9510f8e44127260f92b5b6c3127aafa22b15f741);
Distribution: Xubuntu 18.04.1 amd64.
