[Bug 21796] Syberia game can`t start normally

https://bugs.winehq.org/show_bug.cgi?id=21796

--- Comment #49 from [e-mail]  ---
Finally the demo does not work as good I said in my last comment:
- no black window at start
- no crash after the cinematics
- I can play the game but...
If I go to the menu, new game, the game crash and my desktop becomes all black
(gamma change?).
I have to launch nvidia-settings to recover normal color.
But after that, I have to reboot my computer because my system is a little
unstable, for example: I can no more launch Syberia (does nothing).
Not only the Linux users have difficulty with this game but Windows users too.
They use Dgvoodo to play this game.
