The game is from the same developer as Bermuda from bug #39093, however, this
looks like a different issue and the hack/patch from that bug report doesn't
help.
The game is starting and music begins to play which sounds like the main menu
theme, but no visible window is created and the game constantly uses 70-80%
CPU.
In virtual desktop mode I can only see the empty VD, in fullscreen mode the
game icon is present in the taskbar, but clicking on it has no effect.
Tested under Gnome 3 and XFCE 4.12 (no compositor).

The problem can be reproduced with the demo version available on Steam. After
installation the demo can be launched without Steam running (but corefonts need
to be installed).

Maybe unrelated, but I have similar problem with another game in bug #35243.

Fedora 22 32-bit
