Problem description
When running the pylibfreenect multiframe_listener.py example the cv2.imshow window doesn't show icons. I also raised an issue on the repository of the pylibfreenect package but as I am not sure if the problem has to do with a missing pylibfreenect or opencv dependency I also opened a topic here.

Troubleshooting steps
I am currently looking at whether a system icon package is missing and whether this is a bug related to opencv.
What I already tried
- Installing opencv from different channels:
pip install opencvconda install opencvconda install opencv-pythonInstalling GTK and VTK as explained in this topic.
