partially no image when enabling postprocessing

If I set "postprocessing" in the settings, I'm doesn't see anything of the map, and become the following log-messages:

I'm working on Ubuntu 14.04 with an intel graphic card. The Bug appear on the current dev-version

GLSL has to be enabled first.

I have had the same issue aswell. Solution is to tick options and restart the game. Maybe add a popup when enabling GLSL ?

I have the same problem with GeForce 610M. Please check the video: ​https://www.youtube.com/watch?v=k1yw7TA7oY4

Thanks for the video! I can confirm that enabling postprocessing while a game is already in progress results in blackness which only excludes the GUI and unit silhouettes.

#2672 already has the patch for this.
