MAVGAnalysis: In-Flight Analysis Tool for PX4

Hello
I’ve just tried to use MAVGAnalysis, latest version, downloaded binary.
I have installed MAVProxy to send the Mavlink messages from the Pixhawk (connected with USB) to UDP.
Have tested MAVProxy with QGroundControl and works fine.
Now when I launch MAVGAnalysis it appears to be recevingdata, but the screen flickers and nothing is displayed. The flickering is caused by the details tab appearing and disappearing constantly.

I experienced the same behaviour in both Linux (Ubuntu 14 LTS) and MacOS El Capitan.

Any tips on what could bet going on?
Thanks

This is the screen output on Mac
