Do you have managed to fix it by now?
GOG support wrote me this but it didn't help, so I just contacted FreeLives' support.
1) Make sure you are running the latest version of the game. You may need to download it again from your GOG library:
https://www.gog.com/account 2) Please update your graphics device drivers.
3) Uninstall the game and reinstall it to the default directory, proposed by the installer. DO NOT UNDER ANY CIRCUMSTANCES USE A ROOT TERMINAL OR THE SUDO COMMAND TO RUN THE INSTALLER.
(To uninstall the game, use the uninstall script from the game's installation folder, located by default in '~/GOG Games/<your game>' - double-click it in your usual files browser, or start it from a command line with ./uninstall-<your game>.sh .)
4) Please go to the game's options file (default: <path-to-game>\Saves\Options.xml). Open Options.xml file using text editor and change these values to:
<hasManuallySetPostFX>true</hasManuallySetPostFX>
<cameraPostFXLevel>1</cameraPostFXLevel>
<vSync>true</vSync>
Save the file and start the game.
If above steps didn't resolved your issue, then please contact official support since they should know more about this issue:
