Bug ID: 42290
           Summary: Dota 2 Workshop Tools does not run at all
           Product: Wine-staging
           Version: 2.0-rc5
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

Created attachment 57006
  --> https://bugs.winehq.org/attachment.cgi?id=57006
Output from running step 7 on terminal

Specs:

Arch Linux
Wine 2.0-rc5

Reproduction:

1. Install Linux Dota 2 using Steam for Linux
2. Install Steam for Windows using Wine on a clean 64 bit wineprefix
3. cp --reflink=all steamapps from Steam for Linux to Steam for Windows
4. Launch Steam for Windows, login and let it update Dota 2
5. Make sure that the DLC Dota 2 Workshop Tools are checked
6. cd to Steam for Windows steamapps/common/dota 2 beta/bin/win64
7. env WINEPREFIX='/home/feanor/steam-wine' wine  ./dota2cfg.exe -steam -dx11

Expected result:

Dota 2 workshop tools launch and I can create a mod

What actually happens:

Nothing is happening on the screen, while the dota2cfg.exe eats up 1 CPU core

Output log is attached below
I will retry with 2.0-rc6 when pacman already have it

Note: Step 3 is probably not necessary, you can directly install Dota 2 on
Steam for Windows and follow step 5 onwards, but I don't have enough hard disk
space for that
