eidolies: Linux build gog_dex_2.0.0.1.sh starts, goes into fullscreen but keeps displaying a black screen (tried for 5 minutes) until I Alt+F4. This is on Xubuntu 16.04 amd64. Not sure how to debug it. I also tried from the game/ directory.  
 dex/$ ./game/Dex.x86 
 Set current directory to /mnt/disk/games/dex 
 Found path: /mnt/disk/games/dex/game/Dex.x86

  Also, there is a Unity Player.log file that should be located in /home/<your user name here>/.config/ just look for the developer's name, in this case Dreadlocks.
