cant print to console anymore ROS_INFO or std::cout

edit

Whenever I try publishing an output to the command line in my node I receive the following error:

"Attempt to set a screen on a child window."

I couldnt find any help on my particular problem online. The strange thing is that the output to the console worked fine with either ROS_INFO or std::cout some weeks back. I didnt use it since and cant think about any things I have changed which causes this error. Maybe someone on here knows. The output on the console of the ros node on the start up is this:
