Bug ID: 44312
           Summary: Divinity: Original Sin 2 (Steam) Does Not Launch
           Product: Wine
           Version: 3.0-rc5
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P2
         Component: directx-d3d

Direct DoS2 start with Wine 3.0 rc-5, channels +d3d,+dxgi,+d3d11

Under Wine 3.0-rc5, after DoS2 is successfully installed, and is launched,
Steam reinstalls .net 4.0 every time, as if the previous .net install is not
seen or recognized.  No matter how many times you launch the game, Steam
attempts to install .net 4.0.  After that there is no startup (at all) under
Steam, the game just dies.

If however you start DoS2 directly under Wine 3.0-rc5 using:

/home/test/.local/share/wineprefixes/Testing/drive_c/Program Files
(x86)/Steam/steamapps/common/Divinity Original Sin 2/bin/EoCApp.exe

Then the game attempts to start but has a black screen.  The cursor changes to
the game cursor and then that is all.  This seems to happen to AMD (amdgpu)
users only; Nvidia users do not seem to have this problem and they are able to
run the game with the Nvidia factory drivers.  Please find attached a
+d3d,+dxgi,+d3d11 log (by Józef Kucia's request).

I am submitting this in the hopes this will be fixed before the production
version of 3.0 is released.
